outfile [filename ]<br />
Output light curve or spectrum file name.<br />
outtype [string ]<br />
Chooses output format of either light curve (outtype=“LC”), spectrum (outtype=“PHA”,<br />
“PHA1”, “PHA2”), detector plane histogram (outtype=“DPH”), detector plane image (outtype=“DPI”),<br />
or detetector plane image table (outtype=“DPITAB”). <strong>The</strong> difference between<br />
DPI and DPITAB is that DPI output has one detector image per FITS image extension and<br />
the later has one image per FITS row in a single extension.<br />
timedel = 1.0 [real ]<br />
Select a time bin size, in seconds. If time binning is uniform, then a value of timedel=0.0<br />
causes the tool to accumulate all data into a single time bin. If time binning algorithm is<br />
“snr”, then a non-zero bin size indicates the maximum bin size regardless of the signal to<br />
noise ratio. A zero value of timedel indicates no maximum bin size.<br />
timebinalg = uniform [string ]<br />
One of “uniform”, for uniform binning, “snr”, for constant signal to noise ratio, “gti” for time<br />
binning according to the intervals in the GTI file, “infile” to mimic the input file binning<br />
(binned input data only), or “matchlc” to match an existing light curve. Only the first<br />
character of the algorithm type needs to be specified.<br />
energybins = “-” [string ]<br />
Energy bin ranges, expressed as a comma-separated list of floating point number ranges, a<br />
file name containing energy bin ranges, INFILE, FILEBINS or CALDB.<br />
Comma-separated list Each bin in the comma-separated list is specified as EMIN1-<br />
EMAX1,EMIN2-EMAX2,... (in units of keV). Pulse heights which satisfy EMIN[n] ≤ E<br />
< EMAX[n] are considered to be in bin n. If EMIN[n] is missing, then it is assumed to<br />
be 0. If EMAX[n] is missing it is assumed to be the maximum energy. A value of “-”<br />
indicates single all-inclusive energy bin. At least one bin must be given to make even a<br />
light curve, and bins must not overlap.<br />
File name <strong>The</strong> name of a FITS file with an EBOUNDS extension (such as a response<br />
matrix), containing columns E MIN and E MAX (in keV), or an ASCII file containing<br />
a comma-separated energy bin list as described above.<br />
FILEBINS or INFILE FILEBINS or INFILE indicates that the energy binning of the<br />
first input file is used. (this only applies when the inputs are DPHs, and the DPH must<br />
have an EBOUNDS extension).<br />
CALDB If CALDB is specified, then the CALDB database is consulted for energy bins. A<br />
standard 4-channel and 80-channel set of binnings is chosen depending on whether the<br />
outtype is LC or PHA, respectively. By using CALDB:n, a specific n-channel binning<br />
can be selected (provided it exists in CALDB).<br />
(gtifile = NONE) [string ]<br />
Name of goodtime interval file or time bin file. If the time binning algorithm is “gti” or<br />
“matchlc” then this file is used to establish the time bins. Normally, this file is a standard<br />
GTI. However, for time binning algorithm “matchlc”, this file should be standard OGIP light<br />
curve. <strong>The</strong> user-supplied good times are logically intersected with the good times of the input<br />
files (i.e. only overlap portions are used). <strong>The</strong> default of NONE implies that all good time<br />
intervals from the input files will be used.
