AHELP for CIAO 4.13 Sherpa v1

unpack_rmf

Context: data

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.
