mDiffExec1
Re-project and mosaic your images, with background rectification
Usage
mDiffExec [-p
projdir]
[-d]
[-n(o-areas)]
[-s
statusfile]
diffs.tbl
template.hdr
diffdir
Overview
Runs mDiff on all the pairs identified by mOverlaps.
Options
-
-p projdir -
Specifies path to the directory containing reprojected input images.
-
-d -
Turns on debugging.
-
-n -
No-area-images flag. Creates difference image without requiring
_areaFITS images
-
-s statusfile -
Output and errors are sent to statusfile instead of to stdout
Arguments
diffs.tbl
|
Table generated by mOverlaps for the images in projdir. |
|---|---|
|
FITS header template for output files. |
|
Path to output files. |
Result
FITS images representing the differences for each pair of overlapping images. nimages is the total number of images successfully processed, and nfailed is the number of images that failed. The most likely cause of failure is that the FITS images overlapped, but only in areas where they contained blank pixels (especially common in images with large degree of rotation).

Examples
First, diffs.tbl is generated using mOverlaps. Then mDiff can be run on reprojected images, using this template.hdr.
- $ mDiffExec -n -p projdir projdir/diffs.tbl template.hdr diffdir
-
[struct stat="OK", count=42, failed=0]
