AHELP for CIAO 4.9 Sherpa v1

sherpa_profiles

Context: contrib

Synopsis

Radial profiles of imaging data in Sherpa (CIAO contributed package).

Syntax

from sherpa_contrib.profiles import *

Description

The sherpa_contrib.profiles module provides routines to create radial profile plots of imaging data and fits in Sherpa, 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.profiles import *
from sherpa_contrib.all import *

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

Contents

The profiles module currenly provides the following routines:

Plot a radial or elliptical profile

Routine Description
prof_data() Plot a radial or elliptical profile of imaging data.
prof_fit() Plot a profile of the fit.
prof_fit_resid() Plot a profile of the fit and residuals.
prof_fit_delchi() Plot a profile of the fit and residuals (units of sigma).
prof_model() Plot a profile of the model.
prof_source() Plot a profile of the source.
prof_resid() Plot a profile of the residuals.
prof_delchi() Plot a profile of the residuals (unots of sigma).

Create a radial or elliptical profile

Routine Description
get_data_prof() create the data used by prof_data()
get_fit_prof() create the data used by prof_fit()
get_model_prof() create the data used by prof_model()
get_source_prof() create the data used by prof_source()
get_resid_prof() create the data used by prof_resid()
get_delchi_prof() create the data used by prof_delchi()

Preferences for the profile plots

Routine Description
get_data_prof_prefs() preferences for data profile plots
get_model_prof_prefs() preferences for model profile plots
get_source_prof_prefs() preferences for source profile plots
get_resid_prof_prefs() preferences for residual profile plots
get_delchi_prof_prefs() preferences for residual (sigma) profile plots

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

CHANGES IN THE DECEMBER 2010 RELEASE

Support for set_full_model

The routines in the module have been updated to support source expressions created using the set_full_model() command introduced in Sherpa 4.2 release 2.

Improved behavior when used with un-filtered data

The code has been updated so as not to require a rmin value when used with data with no spatial filters applied.

Bugs

See the bugs pages for an up-to-date listing of known bugs.
