load_xstable_model
(modelname, filename)¶ Load a XSPEC table model.
Create an additive (
atable
, 1) or multiplicative (mtable
, 2) XSPEC table model component. These models may have multiple model parameters.- Parameters
modelname (str) – The identifier for this model component.
filename (str) – The name of the FITS file containing the data, which should match the XSPEC table model definition 3.
- Raises
sherpa.utils.err.ImportErr – If XSPEC support is not enabled.

load_conv
Load a 1D convolution model.
load_psf
Create a PSF model
load_template_model
Load a set of templates and use it as a model component.
load_table_model
Load tabular or image data and use it as a model component.
set_model
Set the source model expression for a data set.
set_full_model
Define the convolved model expression for a data set.

Examples
Load in the XSPEC table model from the file ‘bbrefl_1xsolar.fits’ and create a model component labelled ‘xtbl’, which is then used in a source expression:
>>> load_xstable_model('xtbl', 'bbrefl_1xsolar.fits') >>> set_source(xsphabs.gal * xtbl) >>> print(xtbl)
