MANIPULATING and FLATTENING DPHs
batbinevt can be used to “flatten” detector plane histograms in various ways.
26. Make total DPH (add all DPH rows into a single DPH row).
batbinevt infile.dph outfile.dph DPH 0 uniform infile.dph
(The energy binning of infile.dph means that the energy binning of the input file is preserved
in the output).
27. Make total DPI (add all DPH rows into a single detector image).
batbinevt infile.dph outfile.dpi DPI 0 uniform 14.0-194.9
(Only energies from 14.0-194.9 are kept in the detector image.)
28. Make one DPI for each DPH (flatten by energy)
batbinevt infile.dph outfile.dpi DPITAB 0 infile 14.0-194.9
(“infile” time binning indicates to preserve input file time bins. The output file is a table of
DPIs, one per FITS row). This command creates one DPI per image extension.
batbinevt infile.dph outfile.dpi DPI 0 infile 14.0-194.9
(either is compatible with the batfftimage imaging software)
29. Make new DPHs by collapsing some energy bins. This command makes approximate bins
from 15-25,25-50,50-100 and 100-200 keV.
batbinevt infile.dph outfile.dph DPH 0 infile 14-26,26-51.1,51.1-101.2,101.2-194.9
(Note energy bins must agree to within 0.1 keV of input binning)
It is not advisable to make more than one full-sized (>80 energy channels) DPH because the
memory storage requirements are prohibitive.
