mDiffFitExec(1)

Usage

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

diffs.tbl region.hdr diffdir fits.tbl

Overview

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 parameters.

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.
