NAME
mHdr - Connect to the IRSA service to create a header template
SYNOPSIS
mHdr [-s system] [-e equinox] [-h height] [-p pixsize] [-r rotation] object|location width
outfile
DESCRIPTION
Connects to the IRSA service HdrTemplate to create a header template based on a location,
size, resolution and rotation.
OPTIONS
-s system
Specify a coordinate system. Can be one of:
"equatorial" or "eq" (default)
"ecliptic" or "ec"
"galactic" or "ga"
"supergalactic" or "sgal"
-e equinox
Specify an equinox. Default is 2000.0
-h height
Height (y-axis) of area in degrees. Default is equal to width
-p pixsize
Size of a pixel (in arcsec); default is 1
-r rotation
Rotation of image; default is 0
ARGUMENTS
object|location
Object string or coordinate location; should be in quotes if there are any spaces
or special characters.
width Width (x-axis) of area
outfile
Path to output header template
RESULT
[struct stat="OK", count=header-lines]

EXAMPLES
If a user wants to create a mosaic centered on m31, 1 degree on each side, the first step
is to create a header template that describes the desired mosaic:
mHdr "10.68469 +41.26904" 1 m31.hdr
[struct stat="OK", count=16]
Now m31.hdr can be used by other Montage modules to generate a mosaic.
