mArchiveGet1

Retrieve a single fits image from a remote archive

Usage

mArchiveGet [-d] [-r] remoteref localfile

Overview

Retrieve a single FITS image from a remote archive, using a basic URL GET but with a structured output.

Options

-d

Print additional debugging information.

-r

"Raw" mode - use a raw HTTP GET (no "HTTP/1.1" etc in the header); necessary for communication with some servers.

Arguments

remoteref

URL of remote FITS file to retrieve (should be in quotes). See mArchiveList for more information.

localfile

Full path/filename of the retrieved file.

Result

[struct stat="OK", count="bytes"]

If remoteref points to a g-zipped 2MASS QuickLook image, the image will be unzipped during transfer.

Bugs

The drizzle algorithm has been implemented but has not been tested in this release.

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"]

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.
