cstsmapsplit

Generate commands to split the Test Statistic map computation.

Synopsis

This script generates a sequence of commands to split the Test Statistic (TS) map computation into a distinct number of cttsmap computations. The sequence of commands is written into an ASCII file, where each line in the file corresponds to the command for an individual cttsmap run. Each TS map computed in that way will be suffixed with the command number, and the map can be combined into a single TS map using the cstsmapmerge script.

General parameters

inobs [file]

Input event list, counts cube or observation definition XML file.

inmodel [file]

Input model XML file.

srcname [string]

Name of source model for which the TS map should be computed.

expcube [file]

Input exposure cube file.

psfcube [file]

Input PSF cube file.

edispcube [file]

Input energy dispersion cube file.

bkgcube [file]

Input background cube file.

caldb [string]

Calibration database.

irf [string]

Instrumental response function.

(edisp = no) [boolean]

Applies energy dispersion to response computation?

(errors = no) [boolean]

Compute and store parameter errors?

(statistic = DEFAULT) <DEFAULT|CSTAT|WSTAT|CHI2> [string]

Optimization statistic. DEFAULT uses the default statistic for all observations, which is CSTAT or the statistic specified in the observation definition XML file. CSTAT uses the C statistic for all observations, WSTAT uses the W statistic for all On/Off observations, and CHI2 uses the Chi squared statistic for all binned or stacked observations.

(like_accuracy = 0.005) [real]

Absolute accuracy of maximum likelihood value. Reducing this value will increase the number of iterations and provide a more accurate maximum log likelihood value. Converserly, decreasing the value will result in less iterations at the expense of a less accurate maximum likelihood value.

outmap [file]

Output Test Statistic map file.

bins_per_job [integer]

Number of bins of the TS map that should be computed within one command.

compute_null [boolean]

Pre-computes the null hypothesis globally and passes the value to the individual commands. If the parameter is set to no, the null hypothesis will be computed in each run of cttsmap individually.

(run_in_bkg = yes) [boolean]

Append a & after each command in output file to simply execute the file by running all cttsmap jobs in the background.

outfile [file]

Output ASCII file name where the commands are written to.

(usepnt = no) [boolean]

Use CTA pointing direction for map centre instead of xref/yref parameters?

nxpix [integer]

Number of map pixels in Right Ascension or Galactic longitude.

nypix [integer]

Number of map pixels in Declination or Galactic latitude.

binsz [real]

Map pixel size (in degrees/pixel).

coordsys <CEL|GAL> [string]

Coordinate system (CEL - celestial, GAL - galactic).

proj <AIT|AZP|CAR|GLS|MER|MOL|SFL|SIN|STG|TAN> [string]

Projection method.

xref [real]

Right Ascension / Galactic longitude of map centre (J2000, in degrees).

yref [real]

Declination / Galactic latitude of map centre (J2000, in degrees).

Standard parameters

(chatter = 2) [integer]
Verbosity of the executable:

chatter = 0: no information will be logged

chatter = 1: only errors will be logged

chatter = 2: errors and actions will be logged

chatter = 3: report about the task execution

chatter = 4: detailed report about the task execution

(clobber = yes) [boolean]

Specifies whether an existing output TS map file should be overwritten.

(debug = no) [boolean]

Enables debug mode. In debug mode the executable will dump any log file output to the console.

(mode = ql) [string]

Mode of automatic parameters (default is ql, i.e. “query and learn”).

(logfile = cstsmapsplit.log) [string]

Name of log file.
