Return the background ARF associated with a PHA data set.
This is for the case when there is only one background component and one background response. If this does not hold, use
get_arfand use the
arf – This is a reference to the ARF, rather than a copy, so that changing the fields of the object will change the values in the data set.
- Return type
Simulate a PHA data set from a model.
Load an ARF from a file and add it to the background of a PHA data set.
Load a file as a PHA data set.
Define the convolved model expression for a data set.
Set the ARF for use by a PHA data set.
Set the RMF for use by a PHA data set.
Read in an ARF from a file.
Return the exposure field of the ARF from the background of the default data set:
Copy the ARF from the default data set to data set 2, as the first component:
>>> arf1 = get_bkg_arf() >>> set_arf(2, arf1, bkg_id=1)
