unpack_arf

Synopsis

Unpack an ARF from an ARFCrate

unpack_arf( filename|ARFCrate )

Description

The unpack_arf command unpacks an ARF from a FITS file or an ARFCrate into a Sherpa data object.

If a filename is provided as input, a crate is created but hidden and cannot be used for other analysis in the session.

• filename|ARFCrate - the name of the file (with path) or ARFCrate which contains the ARF data

Example 1

sherpa> arf1 = unpack_arf("arf.fits")

Unpack the ARF into the object "arf1".

Example 2

sherpa> arfcr = read_arf("3c273.arf")
sherpa> arfdata = unpack_arf(arfcr)

The ARF is read into an ARFCrate (named "arfcr") from the file 3c273.arf. The ARF is then unpacked into Sherpa from the crate.
