comlixfit

Fit model to data using SRCLIX algorithm.

Synopsis

This script fits a model to COMPTEL data using the SRCLIX algorithm.

General parameters

inobs [file]

Observation definition XML file.

inmodel [file]

Input model definition XML file.

(suffix = srclix) [string]

Suffix for DRB files. This suffix will be appended to each DRB file so that distinctive file names can be created in the same outfolder.

(outfolder = dri) [string]

Output folder for DRB files.

outobs [file]

Output observation definition XML file.

outmodel [file]

Output model definition XML file.

(outcovmat = NONE) [string]

Output FITS or CSV file to store covariance matrix.

(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?

(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.
