Liens from the 2003 PDS/SBN Asteroids and Comets Review, held May 29, 2003 at PSI, Tucson. Review meeting attendees: Mike A'Hearn, Dan Britt, Tyler Brown, Don Davis, Tony Farnham, Ed Grayzeck (by telephone for the comet data sets), Steve Larson, Barett McGavock (for the SMASS data set), Stephanie McLaughlin (by telephone for the IRAS data set), Carol Neese, Anne Raugh, Andy Rivkin, Mark Sykes, David Tarico (for the SMASS data set), Dave Tholen. Unless otherwise noted, Carol is responsible for resolving these liens. Liens applicable to all data sets ================================= 1. Replace blank missing constants with a missing constant containing one or more characters (such as hyphens) for character data and a numerical value for numerical data. 2. Null value for asteroid numbers will henceforth be zero. 3. CITATION_DESC to be added to data set cats and labels. Mark will generate the values. Asteroid Occultation Diameters and Timings ========================================== 1. Merge the occultation diameters and timings into a single data set. 2. Work with Dunham to firm up vague references. 3. Dan has submitted a list of cases in which the date of an occultation in the diameters file does not correspond correctly with the date of an occultation in the occultations list. Track these down and clear them up. 4. Check with Dunham to find out if the diameter fits were done using the full set of observations reported in the timings file or just a subset. This information should be recorded in the data set. 5. Change the instrument and instrument host to literature compilation. 6. Provide a version number in the data set name. 7. Provide all required keywords in the catalog files. 8. Remove the catalog magnitude from the occultations file. 9. Replace occultation index with a string containing the asteroid name and year. 10. Combine disappearances and reappearances into a single line in the timings file. 11. Define longitude as 0-360 counting east from Greenwich. Convert all longitudes to this convention and document in the label column description. 12. Improve data set cat description to better describe the scope of the collection. 13. Create reference objects for the three star catalogs mentioned. 14. Trim out leading blanks from extra information in the end of the timings file and site file. 15. Take out unnecessary 0 at the end of the times in the timings file. The following suggestions were also made. They are not liens but things that would be good to add if possible. For the diameters file, work with Dunham and/or go back to original papers to get error values on the diameters and quality codes for the entries that lack them. Get the post-1998 timings from Dunham for inclusion in the next update. See if Dunham can supply event depth and filter information on the timings. Some event magnitudes and event codes are missing. Find out if Dunham can supply them. Add the name of the country to the location name. TNO Lightcurves =============== 1. Separate data into one object per file. 2. Ask Sheppard if we can have error bars on the lightcurves. If so, add them to the data set. 3. Remove image number from the data files. 4. For the color lightcurves, get the original color magnitudes from Sheppard and archive that instead of the colors against interpolated R. Put all the data in one file with a column for filter. B and V go in with the R data. This lien contingent on the data being available from Sheppard. 5. Add a column for the error and if a common error is reported, put that in the column. 6. Put all the different lightcurve data into a common format, if possible. Column definitions may vary for different types of magnitude. 7. In the case of too long ref key ids, author's name must be truncated. (Collander-Brown). Stooke Small Bodies Maps ======================== 1. Ask Stooke to give us a description of each of the projections. A few lines each to tell how they work. Add these to the documentation. 2. If Stooke can provide a record of what specific images were used to create each map, add this to the documentation. 3. Make sure that correct instruments and instrument hosts are cited. 4. Make all filenames lowercase. 5. Find out from Stooke how the prime meridian is defined and give this information in the archive. 6. Add labels etc. to make this a PDS-compliant product. Carol, Anne, and Tyler will do this, and we will subsequently have an internal SBN review of the data set before submitting it. SMASS 2 (Bus Spectra) ===================== (Mark is responsible for resolving the liens on this data set.) 1. Unknown items will not be included in the labels. 2. The labels should indicate whether the spectrum is an individual observation or an average. 3. Specify the extinction coefficients used. (Take from the paper and put into the data set cat.) 4. The data set must be made to pass the current version of lvtool. 5. If there is no unit, there must be no UNIT keyword. 6. File names must be ISO-compliant, 27.3. 7. Add an index file to the spectra with parameters of interest to the users. (Action items about OLAF not pertaining specifically to this data set are compiled separately.) TNO Photometry ============== 1. Reformat the data file to have one color per line with a column for the color. Rivkin 3-micron spectra ======================= 1. Add the observational circumstances that are missing from the index table. Andy will send. 2. Take out (91) and (93) from the asteroid name field for Nysa. Radar Detections ================ 1. Reference codes should be left-justified. 2. Take out observer full name from the catalog. Asteroid Discovery Circumstances ================================ 1. Add the errata from MPC to the data set cat. Mike will supply. Asteroid Absolute Magnitudes ============================ no liens. Comet Borrelly Data =================== (Ed is responsible for clearing the liens on this data set.) 1. Images in which the comet was not well imaged or there was too much twilight will be deleted from the data set. Steve will send a list of these images. 2. Add the flat fields and bias images to the data set. 3. Extract any user-needed information from the FITS headers and put them in an accessible part of the data set. Mark and Steve (coordinating with Tony) will between them determine which items are needed. 4. Put the line display direction and sample display direction into the label. 5. Have one data set id which is consistent across the data set. 6. Provide a current ascii version of the focal reducer manual and add it to the document label. 7. Provide instrument host names and ids corresponding to instrument host cats. Refer to the appropriate instrument host in each label. 8. Correct latitude and longitude of the observatory in the labels. 9. Correct the volume id. 10. Correct units for the equation in the data set catalog. 11. Add filter profiles and the DQE of the detector, if available, to the data set. IRAS Tempel-1 Data ================== This data set will need a further review. The review participants made recommendations for the improvements needed before the data set is reviewed again. These recommendations are provided separately. end of liens.
