.SH NAME
mArchiveExec \- Call mArchiveGet on each image in sequence

.SH SYNOPSIS
mArchiveExec [\-d \fIlevel\fP] region.tbl

.SH DESCRIPTION
Given a table of archive images (generated by \fBmArchiveList\fP), calls \fBmArchiveGet\fP on each one in sequence to retrieve all the files into the current directory.

.SH OPTIONS
.TP
\-d \fIlevel\fP
Prints out additional debugging information; in this version, the only supported \fIlevel\fP is 1.

.SH ARGUMENTS
.TP
region.tbl
Table of archive images, generated by \fBmArchiveList\fP.

.SH RESULT
\fB[struct stat="OK", count=\fInum-images\fP, failed=\fInum-failed\fP]\fP
.PP
\fInum-images\fP from \fIregion.tbl\fP are retrieved into the current directory.  \fInum-failed\fP is a count of failed attempts to retrieve images; turn on debugging to see the errors generated by \fBmArchiveGet\fP.

.SH MESSAGES
.TP
OK
[struct stat="OK", count=\fInum-files\fP, failed=\fInum-failed\fP]
.TP
ERROR
Table \fIregion.tbl\fP needs column 'URL' and can optionally have columns 'fname'/'file' and pixel ranges 'imin'...'jmax'

.SH EXAMPLES
.PP
First, run \fBmArchiveList\fP to generate a table of image metadata, including URLs:
.TP
$ mArchiveList 2mass j m31 0.5 0.5 2mass_m31_j.tbl
[struct stat="OK", count=18]
.PP
Next, call \fBmArchiveExec\fP on the metadata table to populate the current directory with the files found by \fBmArchiveList\fP:

.TP
$ mArchiveExec 2mass_m31_j.tbl
[struct stat="OK", count=18, failed=0]
.TP
$ ls

.SH BUGS
The drizzle algorithm has been implemented but has not been tested
in this release.
.PP
If a header template contains carriage returns (i.e., created/modified
on a Windows machine), the cfitsio library will be unable to read it
properly, resulting in the error: [struct stat="ERROR", status=207,
msg="illegal character in keyword"]
.PP
It is best for the background correction algorithms if the area
described in the header template completely encloses all of the input
images in their entirety. If parts of input images are "chopped off"
by the header template, the background correction will be affected. We
recommend you use an expanded header for the reprojection and
background modeling steps, returning to the originally desired header
size for the final coaddition. The default background matching assumes
that there are no non-linear background variations in the individual
images (and therefore in the overlap differences). If there is any
uncertainty in this regard, it is safer to turn on the "level only"
background matching (the "\-l" flag in mBgModel.
