ctlike

Performs binned and unbinned maximum likelihood analysis of CTA data.


Synopsis

Determines source model parameters, such as flux, spectral index, source position, and source extent from a maximum likelihood analysis of CTA data. The analysis can be done in a binned or an unbinned formulation of the log-likelihood function. For binned analysis, a counts map producted by ctbin is required. For unbinned analysis, an events list processed by ctselect is required.

General parameters

  evfile [file]
    Input event list (for unbinned analysis only).
     
  cntfile [file]
    Input counts map (for binned analysis only).
     
  method = BINNED <BINNED|UNBINNED> [string]
    Maximum likelihood analysis method (BINNED - for binned maximum likelihood analysis, UNBINNED - for unbinned maximum likelihood analysis).
     
  (stat = POISSON) [string]
    Fitting statistics (only affects binned analysis).
     
  (refit = no) [boolean]
    Performs refitting of solution after initial fit.
     
  caldb [string]
    Calibration databas.
     
  irf [string]
    Instrument response function
     
  srcmdl [string]
    Source model input XML file.
     
  outmdl [string]
    Source model result XML file.
     

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 source model result file should be overwritten.
     
  (debug = yes) [boolean]
    Enables debug mode. In debug mode the executable will dump any log file output in the console.
     
  (mode = ql) [string]
    Mode of automatic parameters.
