mDiffFitExec - Online in the Cloud

PROGRAM:

NAME

mDiffFitExec - Run mDiff and mFitplane for each record found by mOverlaps

SYNOPSIS

mDiffFitExec [-d] [-l(evel-only)] [-n(o-areas)] [-p projdir] [-s statusfile]

diffs.tbl region.hdr diffdir fits.tbl

DESCRIPTION

Using the table of overlaps found by mOverlaps, mDiffFitExec runs both mDiff and mFitplane
for each record. The fitting parameters are written to a file to be used by mBgModel.

OPTIONS

-d Turns on debugging

-l Only find image background level differences, not slope offsets.

-p Directory containing projected images.

-s statusfile
Writes output message to statusfile instead of to stdout

ARGUMENTS

diffs.tbl
Overlap table generated by mOverlaps, listing all the image pairs that overlap.

region.hdr
FITS header template that was used to reproject the images.

diffdir
Working directory for the difference images.

fits.tbl
Output table of difference paramaters.

RESULT

Generates a table, fits.tbl, containing all the information generated by running mDiff for
the image pairs in diffs.tbl and then mFitplane on each difference image. count is the
number of overlaps in diffs.tbl, diff_failed is the number that generated an error
condition for mDiff, fit_failed is the number that generated an error condition for
mFitplane, and nwarning is the number that generated a warning.

MESSAGES

ERROR Cannot open status file: statusfile

ERROR Can't open output file.

ERROR Invalid diffs metadata file: diffsfile

ERROR Need columns: cntr1 cntr2 plus minus diff

ERROR svc library error

EXAMPLES

First, diffs.tbl is generated for a collection of reprojected images using mOverlap:

$ mDiffFitExec -d -p projected diffs.tbl gal.hdr diffs fits.tbl
[struct stat="OK", count=6, diff_failed=0, fit_failed=0, warning=0]

Output file: fits.tbl.
