get_rmf

Synopsis

Return the RMF associated with a PHA data set.

get_rmf(id=None, resp_id=None, bkg_id=None)

id - int or str, optional
resp_id - int or str, optional
bkg_id - int or str, optional

Examples

Example 1

Copy the RMF from the default data set to data set 2:

>>> rmf1 = get_rmf()
>>> set_rmf(2, rmf1)

Example 2

Retrieve the RMF associated to the second background component of the 'core' data set:

>>> bgrmf = get_rmf('core', 'bkg.rmf', bkg_id=2)

Example 3

Retrieve the ARF and RMF for the default data set and use them to create a model expression which includes a power-law component (pbgnd) that is not convolved by the response:

>>> arf = get_arf()
>>> rmf = get_rmf()
>>> src_expr = xsphabs.abs1 * powlaw1d.psrc
>>> set_full_model(rmf(arf(src_expr)) + powlaw1d.pbgnd)
>>> print(get_model())

PARAMETERS

The parameters for this function are:

Return value

The return value from this function is:

rmf -- This is a reference to the RMF, rather than a copy, so that changing the fields of the object will change the values in the data set.
