UVIS Sample Volume Peer Review Minutes ====================================== Attendees: Lyle Huber David Judd Diane Conner Wayne Pryor Kurt Retherford Mitch Gordon Steve Adams Submitting Comments: John Clarke Mark Vincent Issues: Science issues were discussed first. Issues about missing calibration files were raised and how HDAC and HSP files were calibrated. D. Judd noted that those calibrations are not currently implemented in the software. D. Judd expects documentation in September for HSP but HDAC is unknown. Calibration files for HDAC and HSP files on this volume are place holders. There were some difficulties with the software on the volume. It was unclear to many whether or not both IDL and Java are required. Documentation will be improved to make clear that Java is the only requirement for this software (and that the software is not required to access the data). D. Judd noted that the calibration algorithm already exists in the PDS labels. The INDEX.TAB file for this volume was erroneous. An updated version was available on the UVIS site. K. Retherford brought up more calibration issues, in particular the Steffl et al paper. D. Judd noted that the routines at LASP take into account these issues and generate coefficients into the calibration QUBE. K. Retherford responded that these are wavelength calibrations only and don't account for background subtraction. D. Judd agrees but notes that W. McClintock tells him that background subtraction has not been integrated into the calibration chain. D. Judd says that on July 15th a theoretical paper describing the FUV and EUV calibration will be available with HSP available in September. Actions in this area include D. Judd adding a comment in the SIS about non-nominal calibration and to include in the archive W. McClintock's calibration document. K. Retherford and J. Clarke aksed about how the SPICE information is generated. D. Judd responded that they come from the C Kernels and are converted into the values in the labels. This is documented in the SIS. K. Retherford asks about the pointing accuracy. D. Conner says the accuracy depends on AACS and is currently about 4 milliradians for the spacecraft. Actions include D. Conner putting the pointing accuracy in the INSTHOST.CAT and D. Judd to include in labels which kernels have been used. W. Pryor checked EUV and FUV data and had no problems accessing the data. He found that the calibration curves look great for FUV but something seems to wrong for EUV. W. Pryor also noted that some labels don't seem to have C Kernel/pointing information (the -1000 Right Ascension values, e.g.). The discussion then moved on to PDS archive related issues, most of which can be found in the individual comments; D. Judd and L. Huber should refer to these comments for additional liens not noted in these minutes. SPACECRAFT_CLOCK_STOP_COUNT is not included in the telemetry stream which is why D. Judd has listed all of the values as UNK. However, this should be a simple value to calculate. D. Conner will provide D. Judd with a SCLK/SCET routine? The START_TIME listed in the file corresponds to the end of the first integration, according to W. Pryor and A. Jouchoux. This needs to be carefully documented. L. Huber will provide better examples of AAREADME.TXT and a *DS.CAT file to give D. Judd a better idea of what PDS requires out of these files. All ASCII files need to have characters at the end of every line. L. Huber will send D. Judd a routine to add characters. All files in the DOCUMENT directory need to have ASCII companions. The Space Science Reviews paper seemed to offer an obstacle to D. Judd. If necessary, the Atmospheres Node will provide assistance. D. Judd should provide a bibliography to D. Conner for inclusion in the REF.CAT file. D. Judd will modify the statement in the SIS about scientific validation. There was no opposition to the new wording. L. Huber will provide an index generator routine to D. Judd. S. Adams will take a sample line from the upadted INDEX.TAB, further modify it and create an INDEX.LBL file for D. Judd. M. Gordon will send ring keyword definitions to D. Judd in order to determine the feasibility of including these keywords in the labels. There was a question about eventual data volume size which was resolved. There was some discussion about DATA_SET_IDs vs. calibration issues. New DATA_SET_IDs are not needed just for calibration data. This then raised the issue of identifying TARGET_NAMEs for data files, whether or not certain files should be considered data or calibration, how this is determined, how the E Kernel is generated and how the CIMS request fits in to all this. D. Conner will send D. Judd the E Kernel sample? D. Judd will, prior to the next review of this volume, submit the volume through the CATS software as a test for all parties to CATS. There was further discussion about what properly belongs in the *DS.CAT files. Hopefully the sample will answer these issues. D. Judd noted that he had already addressed the issue of the filenaming convention for the calibration files. The next review should be held in 2-3 months to address these liens.
