Synopsis
Return the data used to create the radial or elliptical profile of fits to imaging data.
Syntax
get_fit_prof( [id], [model=None, rstep=None, rmin=None, rmax=None, rlo=None, rhi=None, xpos=None, ypos=None, ellip=None, theta=None, group_counts=None, group_snr=None, recalc=True] )
Description
The get_fit_prof() command calculates the radial - or elliptical - profile of the imaging data and returns an object containing the values. The profile is defined by the existing model compenents, although it is possible to over-ride these values.
Loading the routine
The routine can be loaded into Sherpa by saying:
from sherpa_contrib.profiles import *
Argument options
The argument options are the same as for the prof_fit() command - except that the overplot and label arguments are not supported - and are described in its ahelp page.
Fields returned by get_fit_prof
The get_fit_prof() call returns an object which contains dataplot and modelplot fields. These values can be seen by using the print command, as shown below. See the ahelp file for get_data_prof() and get_model_prof() for a description of the contents of these fields.
sherpa> d = get_fit_prof(rstep=10) sherpa> print (d.dataplot) sherpa> print (d.modelplot)
Example
sherpa> d10 = get_fit_prof(group_snr=10) sherpa> d = d10.dataplot sherpa> m = d10.modelplot
Extract the data and model components for the plot.
Bugs
See the bugs pages on the Sherpa website for an up-to-date listing of known bugs.
