check this: Need to update PICTLISTR.TXT input file. Need to specify required files/directories to run. needs SUMFILES, NOMINALS, make_sumfiles.txt, etc
Description
This program generates a set of ascii interface files, one for each image, containing optical navigation observables, partials, and relevant ancillary information for use in the FDS navigation software suite(s). Both MIRAGE (KinetX) and GEODYN (GSFC) are currently ingesting these files. A file is created for each image in the restricted picture list, PICTLISTR.TXT, and only landmarks from a restricted landmark list, LMRKLISTR.TXT, are used. If the PICTLISTR.TXT file does not exist, the software defaults to PICTLIST.TXT. Each files contains the following information:
- SPICE IDs, image epoch, camera parameters
- TITV matrix (inertial to camera frame transformation)
- TPMI matrix (body-fixed to inertial transformation)
- SPC solution for:
- Spacecraft-to-object vector
- Camera pointing (RA, Dec, Twist)
- Spacecraft position sigma
- Camera pointing and twist sigmas
- Nominal (a priori):
- Spacecraft-to-object vector
- Camera pointing (RA, Dec, Twist)
- Solar unit vector
- For each landmark identified in the image from SPC process:
- Landmark name
- Body-fixed control point vector
- Body-fixed control point sigma
- Observed landmark center in (pixel, line) image coordinates
- Predicted landmark center in (pixel, line) image coordinates based on nominal S/C position and SPC solution for camera pointing
- Partial derivatives for (pixel, line) w.r.t. spacecraft-body position vector (SCOBJ)
- Partial derivatives for (pixel, line) w.r.t. camera pointing (RA, Dec, Twist)
- List of all SPICE kernels used
regres requires the directory "REGRES_FILES" in the working directory. regres exports files for each picture (<PICTURE NAME>.TXT) to the "REGRES_FILES" directory.
regres uses all pictures in PICTLIST.TXT and landmarks in LMRKLISTR.TXT to make the exported regres files. However, if you have created a PICTLISTR.TXT, regres will only use the pictures from that file.
regres uses data from NOMINAL
