The sherpa.astro.io module

Provide Astronomy-specific I/O routines for Sherpa.

This module contains read and write routines for handling FITS 1 and ASCII format data. The actual support is provided by the selected I/O backend package (currently Crates, provided by CIAO, or the FITS support in the AstroPy package, if installed).

This module should not be imported directly if there is no I/O backend available.
