Contents of the CASSINI Directory
- DATA has all the kernels in it, with no subdirectories. Will also need cumindex.tab (Cumulative Image Index provided by the PDS) in this directory, as well as TABLE.TXT (used to convert images to 12 bit).
- UTILITIES has three files.
list.e - User inputs object name (i.e. DIONE, TETHYS, etc. all caps!!!) and the minimum size of the object in pixels. Use this to flush out low resolution images (list.e scales the size of the body) and make a list of images to download and an input file for the next utility. Source is here list.f
- Note that when running download.b (see below), you may need to first change the curl command to "curl -L" to follow redirects.
convert.e - Enter the object name as "OBJ.TXT" where OBJ is the object name you entered previously. Puts the DAT image files into IMAGEFILES and makes make_sumfiles.in. Source is here convert.f
make_sumfiles.e - Makes the SUMFILES. When it asks if you want to "Include Pole (y/n)" SAY NO!!! Bob toyed with the idea of putting the pole into the SUMFILE, but never implemented that. Source is here make_sumfiles.f
# Below is from Bob's email 29 July 2020 ../CASSINI/UTILITIES/list.e DIONE 100 <- minimum size in pixels [makes DIONE.TXT and b/w coverage plot] [makes ./NEW_IMAGES/download.b] cd NEW_IMAGES chmod +x download.b ./download.b cd .. ../CASSINI/UTILITIES/convert.e <- this is equivalent to PROCESS_IMG DIONE.TXT [makes images and puts into IMAGEFILES] [makes make_sumfiles.in] ../CASSINI/UTILITIES/make_sumfiles.e 0. Create new SUMFILES & NOMINALS and .. 1. Update old NOMINALS and .. 2. Update old SUMFILES 0 Include Pole? (y/n) n <- ALWAYS SAY NO!
