ctselect

Performs sub-selections of event data which are needed for unbinned maximum likelihood analysis.


Synopsis

Creates a new FITS file of selected events from an input event list based on spatial, temporal, and energy cuts. Event selection is mandatory for unbinned maximum likelihood analysis.

General parameters

  infile [file]
    Input event list of observation definition XML file
     
  outfile [file]
    Output event list or observation definition XML file.
     
  (prefix = "selected_") [string]
    Prefix for output event lists in observation definition file.
     
  (usepnt = no) [boolean]
    Use pointing instead of RA/DEC parameters?
     
  ra [double]
    Right Ascension of acceptance cone (or ROI) centre (J2000, in degrees).
     
  dec [double]
    Declination of acceptance cone (or ROI) centre (J2000, in degrees).
     
  rad [double]
    Radius of acceptance cone (or ROI) centre (in degrees).
     
  tmin [double]
    CTA mission elapsed start time defining the earliest event (in seconds).
     
  tmax [double]
    CTA mission elapsed stop time defining the latest event (in seconds).
     
  emin [double]
    Lower energy limit of events (in TeV).
     
  emax [double]
    Upper energy limit of events (in TeV).
     
  (expr = "") [string]
    Additional event selection expression (cfitsio syntax).
     

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 event list should be overwritten.
     
  (debug = no) [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.
