I have noticed that the January 1, 2007 Cassini PDS release is already available, see http://pds-imaging.jpl.nasa.gov/data/cassi...assini_orbiter/
I haven't downloaded all of the imaging data and I'm just beginning to digest what I already have but there are some beautiful images of Enceladus' plumes and satellite mutual events, images of the G and D rings and interesting images of Saturn's nightside and fairly good Iapetus images. Radar and VIMS is also available. All in all a nice 'Christmas gift' . |

There are a few more fields I'd include, in approximate order of priority:
FILTER_NAME_1 FILTER_NAME_2 SUB_SOLAR_LATITUDE SUB_SOLAR_LONGITUDE INST_CMPRS_RATIO DECLINATION TWIST_ANGLE RIGHT_ASCENSION The first five are essential in my opinion. Possibly include VOLUME_ID and some of the RINGS_ fields as well. Note: I'm using the field names from the Access database, not the fields in the INDEX.LBL files (which describe the contents of the INDEX.TAB files from which the database was generated). The field names are usually identical but there are a few exceptions where I broke a field from INDEX.LBL up into two fields, for example the two FILTER_NAME fields (because it seemed more convenient) and the SEC_FRAC fields (because as far as I know the maximum precision of Access dates is one second). I'd use IMAGE_MID_TIME as you did rather than IMAGE_START_TIME. The page layout looks fine but it contains a lot of stuff (42 MB) so maybe it should be broken up into several pages, probably by OBSERVATION_ID. I'll see if I can find out why calibration didn't work for the WA images (it does on my machine when I use my big program from which IMG2PNG was cannibalized). |
