Exceptions

GException::out_of_range	Event index is outside valid range.
GException::invalid_value	Energy vectors have not been set up. Sky directions and solid angles vectors have not been set up.

This method provides the event attributes to the event bin. The event bin is in fact physically stored in the event cube, and only a single event bin is indeed allocated. This method sets up the pointers in the event bin so that a client can easily access the information of individual bins as if they were stored in an array.

void GCTAEventCube::set_directions ( void )

protected

Set sky directions and solid angles of events cube.

Exceptions

GException::invalid_value No sky pixels found in event cube.

This method computes the sky directions and solid angles for all event cube pixels. Sky directions are stored in an array of GCTAInstDir objects while solid angles are stored in units of sr in an array of double precision variables.

A kluge has been introduced that handles invalid pixels. Invalid pixels may occur if a Hammer-Aitoff projection is used. In this case, pixels may lie outside the valid sky region. As invalid pixels lead to exceptions in the WCS classes, we simply need to catch the exceptions here. Invalid pixels are signaled by setting the solid angle of the pixel to 0.

void GCTAEventCube::set_times ( void )

Set mean event time and ontime of event cube.

Exceptions

GException::invalid_value No Good Time Intervals found.

Computes the mean time of the event cube by taking the mean between start and stop time. Computes also the ontime by summing up of all good time intervals.

Todo:: Could add a more sophisticated mean event time computation that weights by the length of the GTIs, yet so far we do not really use the mean event time, hence there is no rush to implement this.

void GCTAEventCube::write ( GFits & fits ) const

Write CTA event cube into FITS file.

Parameters

[in] fits FITS file.

Writes CTA event cube into a FITS file. The following HDUs will be written

 COUNTS - Counts cube
 WEIGHTS - Weights for each counts cube bin
 EBOUNDS - Energy boundaries
 GTI - Good Time Intervals

The counts cube will be written as a double precision sky map. The weighing cube contains the weight for each counts cube, computed as the fraction of the event bin that has been selected in filling the counts cube. This allows to account for proper stacking of observations with different energy thresholds, or different regions of interest. The energy boundaries for all counts cube layers are also written, as well as the Good Time Intervals that have been used in generating the counts cube.
