plot_instmap_weights

Synopsis

Plot up the model spectrum in the form required by mkinstmap

plot_instmap_weights( [id=None, fluxtype="photon"] )

Description

The plot_instmap_weights() command creates a plot of the current model values in the form expected by the CIAO mkinstmap tool. Please see the Calculating Spectral Weights thread for further information on how to use this routine.

Loading the routine

The routine can be loaded into Sherpa by saying:

from sherpa_contrib.utils import *

Arguments

Example 1

sherpa> plot_instmap_weights()
sherpa> log_scale()

Create a plot of the model weights for the default dataset and then change to a logarithmic scale for both axes.

Example 2

sherpa> plot_instmap_weights(fluxtype="erg")
sherpa> log_scale(Y_AXIS)

Here the weights are for use in creating an instrument map in units of cm^2 count / erg rather than the defaulf of cm^2 count / photon.

Bugs

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