CASSINI Procedures

To ingest images, you first need to setup the directory. The programs are (to JRW's knowledge) unique to CASSINI.

Directory Structure

Saturn

• CASSINI
  • DATA
  • UTILITIES
• Dione
• Mimas
• Etc

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.) 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.
  • 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.
  • make_sumfiles.e - Reads make_sumfiles.in and... wait for it... makes the sumfiles.

DIONE
100   <- minimum size in pixels
  [makes DIONE.TXT and b/w coverage plot]
  [makes ./NEW_IMAGES/download.b]
