Synopsis
Create a RMF data structure.
Syntax
unpack_rmf(arg)
Examples
Example 1
>>> rmf1 = unpack_rmf("rmf1.fits")
>>> rmf2 = unpack_rmf("rmf2.fits")Example 2
Read in a RMF using Crates:
>>> acr = pycrates.read_rmf("src.rmf")
>>> rmf = unpack_rmf(acr)Example 3
Read in a RMF using AstroPy:
>>> hdus = astropy.io.fits.open("src.rmf")
>>> rmf = unpack_rmf(hdus)PARAMETERS
The parameter for this function is:
| Parameter | Definition |
|---|---|
| arg | Identify the RMF: a file name, or a data structure representing the data to use, as used by the I/O backend in use by Sherpa: a rmfcratedataset for crates, as used by CIAO, or a list of AstroPy HDU objects. |
Notes
The `minimum_energy` setting of the `ogip` section of the Sherpa configuration file determines the behavior when an RMF with a minimum energy of 0 is read in. The default is to replace the 0 by the value 1e-10, which will also cause a warning message to be displayed.
Bugs
See the bugs pages on the Sherpa website for an up-to-date listing of known bugs.
