sherpa.astro.ui.plot_bkg_source(id=None, lo=None, hi=None, bkg_id=None, replot=False, overplot=False, clearwindow=True, **kwargs)

Plot the model expression for the background of a PHA data set.

This function plots the model for the background of a PHA data set. It does not include the instrument response (the ARF and RMF).

  • id (int or str, optional) – The data set that provides the data. If not given then the default identifier is used, as returned by get_default_id.
  • lo (number, optional) – The low value to plot.
  • hi (number, optional) – The high value to plot.
  • bkg_id (int or str, optional) – Identify the background component to use, if there are multiple ones associated with the data set.
  • replot (bool, optional) – Set to True to use the values calculated by the last call to plot_bkg_model. The default is False.
  • overplot (bool, optional) – If True then add the data to an exsiting plot, otherwise create a new plot. The default is False.
  • clearwindow (bool, optional) – Should the existing plot area be cleared before creating this new plot (e.g. for multi-panel plots)?
