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.

Basic FTOOL Parameter Usage

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.
