Description:
This application
creates a copy of the specified input catalogue. If the input catalogue does not include any WCS
information, then the WCS information from a specified reference catalogue is included in the output
catalogue.
A typical use is to add WCS information back into a catalogue that has been modified using STILTS or
TOPCAT. For instance, if STILTS or TOPCAT is used to create a new catalogue containing vectors
selected from an input POLPACK catalogue, then the new catalogue created by STILTS or TOPCAT
will not contain WCS information in a form that can be used by POLPACK, KAPPA or GAIA. This
application can then be used to add WCS information back into the catalogue created by STILTS or
TOPCAT, copying the WCS from the original POLPACK catalogue.
Usage:
polwcscopy in out ref
Parameters:
IN = LITERAL (Read)
The name of the input catalogue. A file type of .FIT is assumed if
none is provided.
OUT = LITERAL (Write)
The name of the output catalogue. A file type of .FIT
is assumed if none is provided. This will be a copy of IN. If IN contains no WCS, then
the WCS in OUT will be copied from REF.
REF = LITERAL (Read)
The name of the
input catalogue from which WCS is to be read. A file type of .FIT is assumed if none is
provided. An error is reported if this catalogue does not contain any WCS information.
