make_sumfiles

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. 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

 ~/bin/e.make_sumfiles 
 Use B-Frame? (y/n)
n
 0.  Create SUMFILES & NOMINALS and ..
 1.  Update old NOMINALS and ..
 2.  Update old SUMFILES 
0

Output

PICTLIST.TXT
NOMINALS - nominal navigation information and uncertainties
SUMFILES - camera properties and navigation information

Example for Mercator

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)
