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

Output

• PICTLIST.TXT - list of pictures

• NOMINALS - nominal navigation information and uncertainties

• SUMFILES - camera properties and navigation information

Example for Mercator Mission

• Image name (the name of the image in pgm format, and stored in [NEW_IMAGES])

 A1_05

• Image time

 410256.22608  (this is GPS time, but sometimes UTC is used)

• Camera Location

 31.69495, -110.62658, 17716.61873  (for Mercator, this is Lat/Lon and altitude of the aircraft)

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).
