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. 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].

Builds the sumfile and nominals

B-Frame let's you set the NOM and SUM to the body fixed frame.

You must update the ck and spk entries in make_sumfiles.txt. You must have entries that cover the time of all of your images.

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

• 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)
