|AHELP for CIAO 4.9 Sherpa v1||
Utility routines for Sherpa (CIAO contributed package).
from sherpa_contrib.utils import *
The sherpa_contrib.utils module provides utility routines for Sherpa users, and is provided as part of the CIAO contributed scripts package.
The module can be loaded into Sherpa by saying either of:
from sherpa_contrib.utils import * from sherpa_contrib.all import *
where the second form loads in all the Sherpa contributed routines, not just the utils module.
The utils module currenly provides the routines:
|renorm()||Change the normalization of a model to match the data.|
|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|
|estimate_weighted_expmap()||Return the estimated exposure map value by weighting the ARF by the spectral model|
See the ahelp file for the routine and the contributed scripts page for further information.
The renorm() function was added.
The estimate_weighted_expmap() routine has been updated to work in CIAO 4.8.
The file created by this command now includes some basic metadata for use with fluximage, flux_obs, and merge_obs.
See the bugs pages for an up-to-date listing of known bugs.
