AHELP for CIAO 4.9 Sherpa v1

set_arf

Context: data

Synopsis

Set an ARF dataset

Syntax

set_arf( [id], arf, [resp_id=1, bkg_id=None] )

Description

The set_arf command assigns an ARF to a dataset.

  • id - the id of the dataset to use; if not given, uses the default dataset id (id=1 by default, see "ahelp get_default_id")
  • arf - an ARF dataset, e.g. created by unpack_arf ("ahelp unpack_arf")
  • resp_id - the id of the response, if multiple responses exist for the dataset; default is id=1
  • bkg_id - the id of the background, if the response is a background response; default=None

Example 1

sherpa> arf1 = unpack_arf("arf.fits")
sherpa> set_arf("src", arf1)

Create a Sherpa dataset called "arf1" from the file arf.fits. It is then assigned as the first response for the dataset "src".

Example 2

sherpa> set_arf( 2, myarf, resp_id=3)

Set the data in "myarf" as the third ARF of dataset 2.
