Generates pull distribution for all model parameters.
Synopsis
Generates pull distributions for all parameters in a model. The pull is defined by the fitted value minus the simulated true value, devided by the statistical uncertainty. For unbiased parameter estimates, the pull distribution should follow a Gaussian centred on 0 and a sigma parameter of 1.
General parameters
- inobs [file]
- Event list, counts cube, or observation definition XML file.
- inmodel [file]
- XML file that describes the astrophysical sources and the instrumental background.
- outfile [file]
- ASCII file containing the individual pull values.
- caldb [string]
- Calibration database.
- irf [string]
- Instrumental response function.
- (deadc = 0.95) [real]
- Average deadtime correction factor.
- (edisp = no) [boolean]
- Apply energy dispersion to response computation?
- (profile = no) [boolean]
- Use likelihood profile method for errors?
- ntrials [integer]
- Number of samples for generating the pull distribution.
- ra [real]
- Right Ascension of CTA pointing (J2000, in degrees).
- dec [real]
- Declination of CTA pointing (J2000, in degrees).
- coordsys <CEL|GAL> [string]
- Coordinate system (CEL - celestial, GAL - galactic).
- proj <AIT|AZP|CAR|MER|MOL|STG|TAN> [string]
- Projection method.
- emin [real]
- Lower energy limit of events (in TeV).
- emax [real]
- Upper energy limit of events (in TeV).
- enumbins [integer]
- Number of energy bins (0=unbinned).
- (tmin = 0.0) [real]
- Start time (in seconds).
- tmax [real]
- Stop time (in seconds).
- npix [integer]
- Number of pixels for binned analysis.
- binsz [real]
- Pixel size for binned analysis.
- (rad = 5.0) [real]
- ROI radius (in degrees).
- (pattern = single) [string]
- Pattern for pointing simulation (single/four).
- (offset = 1.5) [real]
- Observation pattern offset (in degrees).
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 counts cube 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 = cspull.log) [string]
- Log filename.
