Hi Lyle- here are my initial comments after a day of working on it. Recall I have played with the data before, but not in the PDS format. The raw data I tried looks ok, but I think the geometry has issues. I will look at the calibration stuff before the meeting. -Wayne Wayne Pryor initial comments for UVIS PDS review downloaded, unzipped, tarred data ok. Seems like a complete set of Jupiter encounter data. Opened readme.txt file in reader. Note ObjectReader.jar in the java line should be changed in 2 places to ReadPDSObject.jar java program ran, created idl program. (I'm running on a Mac under OSX 10.3.4) I used IDL, tested EUV data from day 280 (I know this data set). /PDS/DATA/D2000_280/EUV2000_280_03_09.DAT Data looks like interplanetary hydrogen and helium, as it should be. Choice has been made to retain 1024 elements in wl direction even when data is returned as 128 elements- storage issues (lots of 0's in archive)? Should a wavelength scale be available for each of the different binning options? Is it? Looked at metadata structure. Tried to look at geometry (right ascension, declination). Returns -1000, so pointing geometry is NOT associated with the data. On the other hand, central_body_distance, subsolar lat, lon, and subspacecraft lat, lon are present. Is the central body assumed to be Jupiter for all of this data? Phase angle returns NaN. Timing- Alain Jouchoux has told me before that start times in the UVIS database refer to the end of the first integration: is that true here, too?
