make_sumfiles

Compiled by KD

Description

In general, make_sumfiles ingests images into SPC. It takes in, as a standard input, the name and camera position of the images from make_sumfiles.in. It will convert the image into the <filename>.DAT format in IMAGEFILES. It will also generate <filename>.SUM in SUMFILES and <filename>.NOM in NOMINALS. Finally, it will append the image name onto PICTLIST.TXT.

In other words, make_sumfiles builds the sumfiles and nominals. The user should know that all the vectors in the sumfiles and nominals are in a body fixed frame with the origin at the center of the target body (the origin might be off a little bit, which means shift will have to be used eventually). Furthermore, for make_sumfiles to work, the ck and spk kernel names in make_sumfiles.txt must cover the time span of all the images being ingested.

This program is non-standard. While the goal is to make a single version that does it all, each mission has a different image format. This program frequently has different versions for different missions to get the data in a form usable by SPC.

Input Files

• Spice kernel file (SPICE)

• make_sumfiles.txt - list of SPICE kernels

• make_sumfiles.in - list of files from process_img

Input stdin

• if 0 is selected - routine does as description suggests and ends
• if 1 is selected - routine does as description suggests and ends
• if 2 is selected - the following questions need to be answered:

           Update UTC? (y/n)
           Update image thresholds? (y/n)
           Update camera parameters? (y/n)
           Reset geometry? (y/n)
           Reset sigmas? (y/n)

Output

• IFRAME.TXT - picture properties

• PICTLIST.TXT - list of pictures

• NOMINALS - nominal navigation information and uncertainties

• SUMFILES - camera properties and navigation information

Alternative Description

Combines the converted image file with the image number, spacecraft state, spacecraft position & velocity and pointing information along with the associated calculated errors (Sigmas).
