Unpack PHA data from a PHACrate
unpack_pha( filename|PHACrate, [use_errors=False] )
The unpack_pha command unpacks PHA data from a FITS file or a PHACrate into a Sherpa data object. Unpack_pha always returns a list of PHA datasets, in order to handle both Type I and II PHA files. To select specific elements after unpacking, use the syntax file, file, etc.
If a filename is provided as input, a crate is created but hidden and cannot be used for other analysis in the session.
- filename|PHACrate - the name of the file (with path) or PHACrate which contains the PHA data
- use_errors - read the statistical errors from the PHA file? default=False
sherpa> pha1 = unpack_pha("pha.fits")
Unpack the spectrum into the object "pha1".
sherpa> phacr = read_pha("3c273.pha") sherpa> phadata = unpack_pha(phacr)
The spectrum is read into an PHACrate (named "phacr") from the file 3c273.pha. The data is then unpacked into Sherpa from the crate.
