D.1. BATBINEVT 101
batbinevt infile.evt outfile.lc LC 0.1 uniform 15-195 tstart=$START tstop=$STOP
(only include data from $START to $STOP)
6. Applying your own binning (0.1 second uniform bins, 15-195 keV) (must make a Good Time
Interval (GTI) named mygti.gti)
batbinevt infile.evt outfile.lc LC 0.1 gti 15-195 gtifile=mygti.gti
(The “gti” time binning means that the bins are taken from the GTI file. When the time
binning is not “gti” the GTI file is still useful to select data by time.)
7. Unweighted light curve (with no background subtraction)
batbinevt infile.evt outfile.lc LC 0.1 uniform 15-195 weighted=no
(The weighted parameter decides whether mask weighting is applied or not.)
8. Change output units to counts instead of counts/s.
batbinevt infile.evt outfile.lc LC 0.1 uniform 15-195 outunits=count
(The outunits parameter can be either COUNT or RATE.)
MAKING SPECTRA from EVENT DATA
9. Total spectrum, in user-specified energy bins
batbinevt infile.evt outfile.pha PHA 0 uniform 15-25,25-50,50-100,100-195
(A time bin size of 0 means that the entire data set should be accumulated into one total
spectrum.
The energy bins can be specified as either an ASCII list or a file name with the energy bins.
With a few bins it is easier to give an ASCII list.)
10. Total spectrum, with energy bins given by EBOUNDS extension in myebounds.fits
batbinevt infile.evt outfile.pha PHA 0 uniform myebounds.fits
(Here the energy bins are given in a file with an EBOUNDS extension.)
11. Spectrum every 100 seconds, using EBOUNDS extension
batbinevt infile.evt outfile.pha PHA 100.0 uniform myebounds.fits
