AHELP for CIAO 4.11 Sherpa v1

load_xszmshift

Context: models

Synopsis

Redshift a multiplicative model. XSpec convolution model *Experimental*.

Description

This convolution model redshifts a multiplicative model. It takes the calculated model and shifts energies by 1/(1+z).

xszmshift Parameters

Number Name Description
1 Redshift Redshift

Loading the X-Spec convolution models

Please see ahelp xsconvolve for information on how to load the model.

Notes

XSpec version

This information is taken from the XSpec User's Guide. Version 12.10.0e of the XSpec models is supplied with CIAO 4.11.


Example

sherpa> from sherpa_contrib.xspec.xsconvolve import load_xszmshift
sherpa> load_xszmshift("zms")
sherpa> set_source(xsphabs.gal * zms(xsphabs.zgal) * xspowerlaw.pl))
sherpa> zms.redshift = 0.25

The power-law is multiplied by both a redshifted (zgal) and local (gal) absorption.
