NAME

applyxform - transforms a list of coordinates

USAGE

applyxform infile=<string> transform=<string> outfile=<string>

DESCRIPTION

This tool calculates the transformed coordinates corresponding to a list of input coordinates.

PARAMETERS

infile [string]

The file containing the list of original coordinates. These are specified as a space-separated list of X and Y coordinates in ASCII. If this parameter is "STDIN" then the tool will read from the standard input.

outfile [string]

The file into which this tool will write the transformed coordinates. For each set of coordinates the tool writes four numbers - the input coordinates followed by the output coordinates. The values are in ASCII separated by white space. If this parameter is set to "STDOUT", the results will be written to stdout.

transform [string]

The FITS file specifying the transform to apply. This file my be generated by the getxform or combinexform tools.

(inprec = 2) [integer]

Digits of precision reporting fractional input pixels.

(outprec = 2) [integer]

Digits of precision reporting fractional output pixels.

(chatter = 1) [integer]

Output verbosity

(history = yes) [boolean]

Write HISTORY keywords to output?
