Liens from the 2006 Asteroid Data Review Attending: Ludmilla Kolokolova, Paul Abell, Mike A'Hearn, Anne Raugh, Rose Early, Carol Neese, David Tarico, Mark Sykes, Steven Adams, Dave Tholen, Dan Britt, Don Davis. Data providers Bea Mueller, Kevin Walsh, and Jianyang Li were present during the discussion of their data sets. Liens on all data sets ====================== 1. Data set terse description should include the time period covered by the data. 2. Documents don't have correct delimiters. Images and Photometry of TNO 29981 ================================== (Liens on this data set will be resolved by Bea Mueller.) 1. Add a line or two in the overview explaining why the images were included in the archive. 2. Identify the standard stars by pixel coordinates and also give the pixel coordinates for the asteroid for each image. These can be listed in a separate file. 3. Convert the lightcurve file times to Julian Date, using an appropriate number of digits of precision. 4. Archive the apparent magnitude rather than the absolute magnitude. 5. Include a column description for the time in the time series tables. 6. Times should not be light-time corrected. S3OS2 Spectroscopic Survey ========================== (Liens on this data set will be resolved by Thais Mothe.) 1. Add a column for the uncertainties in the spectra. 2. Supply a more complete instrument description, including a reference if possible. 3. Exposure count parameter is zero. It should be one or more based on whether multiple spectra have been coadded. 4. Why do integration times in parameter table sometimes not match that reported in the paper? Correct these if they are errors, or document it if it is the paper that is in error. 5. Put integration time in the parameter table into decimal seconds. 6. Start and stop time of the data set catalog do not match the claimed times for the duration of the survey. Correct so they are in agreement. 7. Spectrum labels do not have valid stop times. If the stop time is unknown, UNK is ok, otherwise supply valid times. 8. Give reflectances to an appropriate number of digits of accuracy. 9. Supply airmass of the observation in the parameter table. If possible, supply the range of airmasses over which the observation was taken. 10. If possible, supply all the individual spectra rather than selected and/or combined spectra. 11. Create meaningful subdirectory names for the data files so users can easily find the data they are looking for. 12. Don't use N/A as the value of the abstract description. Just leave it blank and OLAF will omit it from the label. HST Ceres Images and Maps ========================= (Liens on this data set will be resolved by Jianyang Li except where noted.) 1. Add a paragraph in the data set description describing the imaging plan and the coverage across the object. 2. In the confidence level note, remove the sentence reading, "The calibrated HST images are good to be used for all the future photometry work." 3. In the label for the aspect.tab file, column 11 (magnitude), the description should read "disk-integrated magnitude" rather than "total magnitude". 4. Add a clarifying sentence to the data set description that the black parts of the image are nulls or zeros. 5. Convert times in aspect.tab to Julian Date. 6. Add a line to the data set description that there are 30 pixels across Ceres in the images. 7. Citation description should list only the first five authors explicitly, then "and xx others". 8. Use subheadings in the data set description to break it down into sections. (The help page of OLAF lists the PDS-recommended subheadings for data set descriptions, use these if appropriate.) 9. One or more data file has target name "Ceres" instead of "1 Ceres", which propagates into the data set catalog and target catalogs. Correct this. 10. Remove the refkeyid's for the individual products. 11. aspect.tab column five (exp_time), is F4.0, with a decimal point and no following zero. Change it to an integer or to F4.1. 12. Cite the FITS standard in the reference catalog. (OLAF) 13. Supply a reference frame, epoch, and rotation period for the shape model. It can go in the label description. 14. In the data set description, the words "single scattering albedo" should be replaced with "Hapke's single scattering albedo averaged over the surface of Ceres". Binary Minor Planets ==================== (Liens on this data set will be resolved by Derek Richardson and Kevin Walsh.) 1. Add a column to the table to indicate the class of the object (e.g. NEO, main belt, etc.) 2. Sort on asteroid number and provisional designation. 3. Supply the full reference for the paper (now "in press"). 4. Add uncertainties for the parameters in columns 5 through 9 in the table. 5. Add the mass of the system (in kg.) and density where available. Also their uncertainties. 6. The descriptions for columns 3 and 4 should say "semimajor axis of the system" not of the primary. 7. Take out the definition of a major planet from the abstract description, and add the words "and Pluto/Charon" to the description of the scope of the compilation. (I.e. don't describe Pluto as a minor planet.) 8. Add valid start and stop times to the data set cat and to the label. These should reflect the span of time covered by the publication dates of the references cited in the table. For this data set, the start and stop times of the data set cat and of the label should match. 9. Confidence level note should tell the scope of the literature search. (ADS abstract service?) 10. Must have missing constant values in the data file. 11. Need two separate columns for name and provisional designation. 12. Document doesn't have correct delimiters. (OLAF) Torino Polarimetry ================== (The liens on this data set will be resolved by Carol Neese.) 1. Merge the four data tables into one. 2. In the table five description, clarify using the word "derived". (Check with Ludmilla for details.) 3. Supply missing text near the end of the data set description, after the words "followed by..." 4. Require observation dates and times for the entries. Ludmilla will write up a justification to use when contacting Cellino. If this lien can only be partially met, one reviewer (Abell) asked to review the data set again to make sure the resolution is adequate. 5. Supply a reference for the "standard routines" used to reduce the data. Infrared Diameters and Albedos ============================== (The liens on this data set will be resolved by Carol Neese.) 1. Supply more detail on the instrument overview for MIRLIN. In particular, MIRLIN had readout problems early on. Document them if they are applicable to this data set. Paul will send a URL for a JPL website with more MIRLIN information, and Bobby Bus is recommended as a source of information for this instrument. 2. Tell the number of asteroids observed in the data set description. 3. To construct the data set ID, use the ID of the most important instrument slash ETAL. 4. For the label description of column 5 of the diameter table (beaming parameter), tell how the assumed beaming parameters were arrived at and how the value was selected. (Information is in Delbo's thesis.) 5. Ask Delbo to provide uncertainties for the three albedos and the three diameters. 6. There is information in the Delbo thesis under the relevant table about the uncertainty of the derived values. Add this information to the table description. 7. Ask Delbo to review the contents of the notes column and standardize and augment it. For example, if the note says "lightcurve small", what is small? If the note says "nspec" what does this mean? Etc. 8. Make sure the user can tell which entries in the flux table were used to derive each entry in the diameters table. One way to do this would be to add observation times to the diameters file. 9. Both entries for Itokawa in the diameters file have the same date. Probably one is wrong. Check and correct. 10. The NEATM albedo given for one of the entries for Itokawa is unreasonable. Check and correct. 11. Use the cross-id facility to add names and provisional designations where they exist. Data set updates ================ (Liens on the data set updates will be resolved by Carol Neese.) TNO and Centaur Colors ====================== No liens. Asteroid Polarimetric Database ============================== 1. Explain the selection criteria for the data in the data set description (e.g. why no TNO's). 2. Ask Lupishko if he can provide a list of just the papers referenced in the table, with reference codes. If not, Anne says she can write a perl program that will do 95% of the work to create this table. 3. Typo in observatory list: Photometric --> Polarimetric 4. In the filter column description, convert wave numbers to wavelengths in microns. 5. Inconsistency in spelling in data set description: Kharkov University --> Kharkiv National University (as in observatory list). Radar Detections ================ 1. Augment the data set description to describe how the data were collected and by whom. 2. There are two references numbered 45 and none numbered 46. Correct, and check the entries referring to 45 and 46 to make sure they refer correctly. 3. Put the last detection in the table into its proper sort order. Lightcurve Derived Parameters ============================= 1. In the descriptive material, refer to this data set as "rotational parameters derived from lightcurve data". 2. Note in the data set description and label description that the reference numbers are reassigned with each version. Occultations ============ 1. Add a target object for Neptune to the data set. 2. Occlist.tab column 24 (AST_DIAM): The equation assumes an albedo of 0.16. Tell this in the description and put in the expanded equation with albedo explicit (Mark has emailed the correct equation). 3. Document in the column description for column 24 which version of IMPS was used. Names and Discovery =================== 1. Replace ???'s in data set description with actual values. 2. In the modification history and in the first paragraph of the data set description, give the data set id's of the superseded data sets which are mentioned. Astermag ======== 1. Correct the errata which Dave has sent so far. end of liens.
