mHdr(1)

Usage

mHdr {[-s system] [-e equinox] [-h height] [-p pixsize] [-r rotation] [-t 2mass-band] object | location width outfile}

Overview

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

-t 2mass-band: If the data is 2MASS, the correct MAGZP will be added to the header.

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]

Messages

`OK`	[struct stat="OK", count=header-lines]
`ERROR`	Can't open output file outfile
`ERROR`	location parameter required
`ERROR`	width parameter required
`ERROR`	Invalid object/coordinates
`ERROR`	Couldn't find host irsa.ipac.caltech.edu
`ERROR`	Couldn't create socket
`ERROR`	irsa.ipac.caltech.edu: connect failed

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.
