comlixmap

Create TS map using SRCLIX algorithm.

Synopsis

This script generates a Test Statistic map using the SRCLIX algorithm.

General parameters

inobs [file]

Input observation definition XML file.

inmodel [file]

Input model definition XML file.

(inmap = NONE) [file]

Input Test Statistic map file. If a TS map FITS file is specified, information will be extracted from the file for pixels that are contained in that map, avoiding recomputation. This allows for example to enlarge an existing TS map for which the computations will be done on the enlarged section.

srcname [string]

Test source name.

outmap [file]

Output Test Statistic map file.

(max_iter = 50) [integer]

Maximum number of SRCLIX iterations.

(like_accuracy = 0.05) [real]

Absolute accuracy of maximum likelihood value. The SRCLIX iterations terminate if the log-likelihood improvement is below this accuracy.

(accept_dec = 0.0) [real]

Maximum accepted log-likelihood decrease. Setting this parameter to a positive value with allow some decrease of the log-likelihood. This may help to get the algorithm out of a local minimum. Use this parameter with case since it may lead to a solution that is not the maximum likelihood solution.

(fix_spat_for_ts = no) [boolean]

Fix spatial parameters for TS computation?

nxpix [integer]

Size of the X axis in pixels.

nypix [integer]

Size of the Y axis in pixels.

binsz [real]

Image scale (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]

First coordinate of image center in degrees (RA or galactic l).

yref [real]

Second coordinate of image center in degrees (DEC or galactic b).

(nrunav = 3) [integer]

Number of Chi/Psi bins used for running average (relevant for BGDLIXA method).

(navgr = 9) [integer]

Number of Chi/Psi bins used for averaging (relevant for BGDLIXA and BGDLIXE methods).

(nincl = 5) [integer]

Number of Phibar layers to include (relevant for BGDLIXA and BGDLIXE methods).

(nexcl = 0) [integer]

Number of Phibar layers to exclude (relevant for BGDLIXA and BGDLIXE methods).

(phi_first = -1)  [integer]

First Phibar layer for likelihood fitting, starting from 0. If -1 is specified there is no first Phibar layer selection.

(phi_last = -1)  [integer]

Last Phibar layer for likelihood fitting, starting from 0. If -1 is specified there is no last Phibar layer selection.

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 energy boundaries output 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 = comlixfit.log) [filename]

Log filename.
