sherpa_utils

Description

The sherpa_contrib.utils module provides utility routines for Sherpa users, and is provided as part of the CIAO contributed scripts package.

Loading the routines

The module can be loaded into Sherpa by saying either of:

from sherpa_contrib.utils import *
from sherpa_contrib import *

where the second form loads in all the Sherpa contributed routines, not just the utils module.

Contents

The utils module currenly provides the routines:

• save_instmap_weights() - write out the model spectrum in the form required by mkinstmap
• plot_instmap_weights() - plot up the model spectrum in the form required by mkinstmap
• get_instmap_weights() - return the model spectrum in the form required by mkinstmap

Deprecated routine

The following routine is deprecated; users should switch to using the guess() routine instead:

• set_param_limits_from_image() - Set the limits for positional parameters (xpos,ypos) to match the image coordinate range

See the ahelp file for the routine and the contributed scripts page for further information.
