NAME¶

fitscopy - copy FITS files with optional filtering

SYNOPSIS¶

fitscopy inputfile outputfile

DESCRIPTION¶

Copy an input file to an output file, optionally filtering the file in the process. This seemingly simple program can apply powerful filters which transform the input file as it is being copied. Filters may be used to extract a subimage from a larger image, select rows from a table, filter a table with a GTI time extension or a SAO region file, create or delete columns in a table, create an image by binning (histogramming) 2 table columns, and convert IRAF format *.imh or raw binary data files into FITS images.

EXAMPLES¶

simple file copy

fitscopy in.fit out.fit

stdin to stdout

fitscopy - -

copy a subimage

fitscopy in.fit[11:50,21:60] out.fit

IRAF image to FITS

fitscopy iniraf.imh out.fit

raw array to FITS

fitscopy in.dat[i512,512] out.fit

copy rows with pi>35

fitscopy in.fit[events][pi>35] out.fit

bin an image

fitscopy in.fit[events][bin X,Y] out.fit

new x column

fitscopy in.fit[events][col x=.9*y] out.fit

time filter

fitscopy in.fit[events][gtifilter()] out.fit

spatial filter

fitscopy in.fit[2][regfilter("pow.reg")] out.fit

Note that it may be necessary to enclose the input file name in single quote characters on the Unix command line.
