NAME
ftrbnarf -- Rebins an ARF.
USAGE
ftrbnarf infile binfact outfile
DESCRIPTION
This tool compresses a FITS ARF array in energy-space. It is intended
to be used in parallel with the energy-binning option of rbnrmf. The
default operating mode is to bin up by the factor given by the binfact
parameter. If the hidden parameter binfile is set then an ascii file
will be read to get the binning factor(s).
PARAMETERS
- infile [filename]
- Input ARF filename.
- (binfile) [filename]
- An ascii file comprising a list of energy bin ranges and
compression factors eg the line I I+N-1 2 will cause the N energy bins
starting at I to be compressed into N/2 bins. The first bin number is
1. Each triplet of numbers should be on a separate line and they
should be in increasing order of bin number. The ranges need not be
contiguous.
- binfact [integer]
- The compression factor eg if binfact=2 and the input ARF has N
energy bins then the output ARF will have N/2 energy bins. If the
binfile parameter has been set then this parameter is not required.
- outfile [filename]
- Output ARF filename.
- (clobber = no) [boolean]
- Standard HEAdas clobber parameter; controls whether an existing output file may be overwritten.
- (history = yes) [boolean]
- Standard HEAdas history parameter; controls whether the runtime parameter values should be written in block of HISTORY keywords in the output file.
EXAMPLES
1. Bin by a constant factor
ftrbnarf infile=file1.arf binfact=4 outfile=fileout.arf
2. Bin by factors in input file
ftrbnarf infile=file1.arf binfile=binning.txt outfile=fileout.arf');
