Synopsis
Return the RMF associated with a PHA data set.
Syntax
get_rmf(id=None, resp_id=None, bkg_id=None)
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:
| Parameter | Type information | Definition |
|---|---|---|
| id | int, str, or None, optional | The data set to use. If not given then the default identifier is used, as returned by `get_default_id` . |
| resp_id | int, str, or None, optional | The identifier for the RMF within this data set, if there are multiple responses. |
| bkg_id | int, str, or None, optional | Set this to return the given background component. |
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.
