NAME
ftmkfiltrsp - Read an input text with a filter response to make a single
channel response matrix.
USAGE
ftmkfiltrsp infile outfile xunit clobber
DESCRIPTION
This tool reads a text file (infile) which contains the response for a
filter (in cm^2) and creates a response matrix with a single
channel. This is useful for including photometric data in spectral
fitting. The format for the input file is three numbers per row with
the first and second numbers being the start and end energies (or
wavelengths) for the bin and the third the response.
The units for the energies (or wavelengths) in the input
text file can be specified using the xunit parameter. The
allowed units are given below in the parameter specifications.
PARAMETERS
- infile [filename]
- The name of the input text file with the model spectrum or spectra.
- outfile [filename]
- The name of the output response file.
- xunit [string]
- The units for energy or wavelength used in the input text
file. The allowed options are keV (the default), MeV, GeV, Hz,
angstrom, cm, micron, or nm.
- clobber [bool]
- If clobber = yes then overwrite the output file if a file of this
name already exists.
