NAME

src2pha -- Creates a PHA file from specified extensions in an RDF src file

USAGE

src2pha infile outfile specext oahext

DESCRIPTION

Input is a ROSAT RDF *_src.fits file from a PSPC observation) and a choice of spectral and OAH extension numbers. Output is a PHA (spectral) file in the standard form for use with Xspec, pcarf, etc.

PARAMETERS

infile [file name]

The input source file.

outfile [file name]

The output PHA file.

specext [integer]

The extension number for the extension containing spectral information. (Primary HDU is the 0th extension.)

oahext [integer]

The extension number for the extension containing the off axis histogram information. This will almost certainly be = specext+1. (Primary HDU is the 0th extension.)

(chatter = 10) [integer]

How much do you want to know. (0 dead silent: only fatal errors reported, 5 quiet,10 normal,15 high,>20 silly)

(clobber = no) [boolean]

Whether to overwrite an existing output file.
