Liens from the PDS/SBN 2005 Asteroid Review June 16, 2005. Attending: Bobby Bus, Dan Crichton, Dave Tholen, David Tarico, Carol Neese, Tyler Brown, Ludmilla Kolokolova, Mike A'Hearn, Anne Raugh, Beth Clark, Rose Early, Don Davis, Mark Sykes (for 2MASS only), David Lien (for MSX only). S3OS2 Taxonomy ============== 1. Rather than a separate data set, add these data to the existing Asteroid Taxonomy data set. The following are liens on the resulting version of that data set. 2. State in the data set description that the "Tholen types" are "modified Tholen types", particularly with regard to the Caa and K types, which were not used in Tholen's original classification. 3. Confirm that albedo was not used in Lazzaro's classification, and state that in the data set cat if so. 4. When combining the taxonomies, use a consistent treatment for the types referred to as "U" in Lazarro's paper. 5. Check refkeyid's for correctness, some are inconsistent. 6. Add the wavelength range to the data set cat description. Mothe Asteroid Families ======================= 1. Inclination should be sine i for all tables. Current inclination formats suggest that inclination may have been truncated, make sure this isn't propagated into the sine i's. 2. Convert tables to a standard format for each table type. 3. Include asteroid number, name and provisional designation in each data table. Two of the three must be supplied by the data provider. 4. Add a column to the clump files with clump identification. 5. Improve the overview in the data set cat. Give the number of files and describe the organization of the data. 6. Replace the second paragraph in the data set cat description with text along the lines of "For those asteroid that have taxonomic classifications, a table is provided that links the taxonomic class with the family identification." 7. Refer in the data set cat description to the taxonomy data set containing the taxonomies this data set is based on. 8. The distance range stated in the data set cat description is inconsistent. Check and correct. 9. Non-printing characters have been used in the descriptions, resulting in missing letters. Find and correct all such cases. 10. Correct the column descriptions for proper rate of perihelion in all data files. The unit is stated incorrectly, missing a "per year". 11. Correct principal reference, which is no longer in press. 12. Add all references mentioned in the text to the refs.cat. 13. Check all columns to make sure missing constants are handled correctly. 14. Sometimes the same asteroid has a different absolute magnitude listed in different files. Track down the source of this and correct or clarify. 15. Add to the data set cat a description of the file naming convention, including that families are named after a member asteroid. 16. When the above liens have been resolved, distribute the data set to the same reviewers (Clark and Bus) and conduct a follow-up review by email. Telecon not required except in the case of controversy. 2MASS ===== 1. Make sure all references are given in the descriptions, as well as ref.cat. References with more than five authors should list the first five authors. 2. Clarify what 1-d radial profile means in the description of column 5. Have they averaged over azimuths? Mark will check with Cutri. 3. Column 5 and wherever it is repeated, global search on bright star replace with "bright source" since in this case it is an asteroid. 4. Column 5 refers to "Atlas Image", which is presumeably a product of the survey. Find out what it is and clarify or give a reference as appropriate. 5. Columns which claim to have a "null" value should have the missing constant added to the table and label. 6. Get rid of the refkeyid with a URL in it and put that information into the data set description. 7. For all the column descriptions referring to a "default magnitude", remove the word "default". 8. Column 7 "phase angle" should be called "solar phase angle". 9. Add language to the data set description that the orbital elements that were used to predict the asteroid positions are included as the p and q position vectors. 10. Clarify in the data set description that the number given is the number of detections, not the number of asteroids. If the number of asteroids can be determined, include that information as well. Mark will provide a URL source for this information. 11. Correct the 2MASS name in the abstract description by adding the words "All-Sky". 12. In the data set description, K(s) should be Ks. 13. Columns 30 and 31: Replace "minor planet proper motion" with "minor planet apparent motion". 14. Columns 47, 48: Add to the description of absolute magnitude and slope the terms H and G. 15. Add material to confidence level note about the occurance of contamination. Mark will write a paragraph to add to confidence level note. Binary NEOs Summary =================== 1. Redo flags to be mnemonic letters, with no punctuation. Ok to use extra letters and make the table wider if it makes it easier to interpret. 2. Add a caveat to the data set cat, "Check the flags before using these data!" 3. When reassigning flag values, use a note pointer to describe caveats on individual objects where appropriate. 4. Sort table by asteroid number and provisional designation. 5. Correct typo "taxonomical class" --> taxonomic class 6. If particular entries in the table are based on unpublished data, they should be flagged. Check with the observers to make sure we have permission to archive them in PDS and if not, remove them. Note: This data set will be archived as an NEO binary summary table and updated yearly if Pravec is willing to do so. In addition, a new data set will be prepared containing a summary for all binary small bodies, not just NEAs. Wisniewski Absolute Magnitudes ============================== Corrections for Table 1: 1. Label description says "figure 1" instead of "table 1". Correct. 2. Page 397 in the paper is left out of table 1. Restore it, and also check to make sure no others are left out. The start time of this table must also be changed as a result of this. 3. If possible, determine whether column 5 is start time or mid time and document in the column description. 4. Column 10: Units for minutes of declination should be changed to arcminutes. 5. Column 12: Supply unit (degree). 6. Column 16: Add appropriate units. 7. Column 17: Mag flag has a value of r in the table. Find out what it means and document in the column description. 8. Column 21: Supply unit (magnitude). 9. Column 22: Remove the telescope list to a separate file. Spell out inch so OLAF doesn't remove it. Replace p1or3 with p1/p3. Corrections for Table 2: 1. column 5: UV color may have had negative values which would have been truncated. Check and restore. 2. Column 9: Try to find out from Al Harris what the constraints are on "long" periods and document it better. 3. Column 14: Ask Al Harris, "What would make an observation so unreliable as to get a rel code of 1?" Add additional clarification to the definition of the rel code if appropriate. 4. Column 14: Clarify that the reliability code pertains to the period determinations, and move the column to be next to the period column. 5. Column 16: Clarify b-v as "Eight Color Asteroid Survey (ECAS) b-v" and B-V as "Johnson B-V". 6. Column 20: Add the Tholen (1989) reference to the reference list. 7. Column 21: replace the second "given" with "using". 8. Column 21: Add the Harris and Harris (1997) reference to the reference list. 9. Column 23: Check to see whether in any cases where the albedo is assumed based on taxonomic class, the taxonomic class is also assumed. If so insert a warning in the description. MSX Images ========== 1. Replace the support archives mission.cat with the MSX mission.cat. 2. Inst host should list all the MSX instruments and their start and stop times. 3. In the data set cat, spell out the acronym ICBM. 4. Add a line to the inst host cat, "A complete description of the spacecraft is found in Mill et al." with reference. 5. Make a similar reference to the instrument paper in the inst cat. 6. David Lien will supply some additional references for the instrument. Add these references to the inst cat and ref cat as appropriate. 7. If the information can be found, add the fwhm to the band descriptions. Dave Lien may know where this information can be found. 8. Add a line to the data set cat that a transition object has both asteroidal and cometary properties as defined by the authors. 9. Add to the data set cat the pixel size, array size for each band, noise equivalent power, scan procedures, and field of view on the sky. 10. Target names have apparently been garbled by the omission of parentheses. Check them with the names given by the SBN cross-id facility and correct as needed. In the data set description, use the full correct target names. 11. Rearrange the data subdirectories to have a subdirectory for each target, rather than an arbitrary division. 12. The following information must be added to the data labels (in keywords): a) central wavelength b) pixel scale c) ra and dec from the fits header d) data min and max e) line display direction and sample display direction f) celestial north clock angle g) axis order type h) unit keyword in the image object (units of pixel data values) 13. The following information is desired in the data labels and should be added if practical: a) pixel position of object b) heliocentric distance c) geocentric distance d) solar phase angle 14. Create a parameter table of parameters from the images that a user might want to search on. 15. If possible get the other Hyakutake observation on Sept 1996 which is mentioned in the paper but not included in data set. 16. Dave Lien will check to make sure that there is no documentation for the temperature correction factors. If this is true, add a note to the data set cat to this effect. 17. When the above liens have been resolved, distribute the data set to the same reviewers (Lien, Clark, and Bus) and conduct a follow-up review by email. Telecon not required except in the case of controversy. TNO and Centaur colors ====================== 1. In the data set description, take out the words "is considered". SDSS MOC ======== No liens. Asteroid Radar Detections ========================= No liens. Asteroid Lightcurve Parameters ============================== 1. The refkeyid's LAGERQVISTETAL1989 and LAGERQVISTETAL1988 appear to refer to the same paper (in Asteroids II). Determine once and for all what is the correct reference and refkeyid for this paper, correct it in this data set, and submit the correction to EN so the erroneous reference can be removed from the PDS reference data base. 2. Mention the existence of the comments file in the data set description. Asteroid Occultations ===================== 1. Data set description should specify the date through which the data are taken. 2. Correct wording in abstract description: "Some occultations BY planetary satellites are provided." 3. In data set description change the words "asteroid occultation axes" to "asteroid axes". Asteroid Names ============== No liens. Magnitudes and Slopes ===================== No liens. All Data Sets ============= Standards review comments and corrections sent by Tyler separately. end of liens.
