Function Documentation

void addEmcHits

(

bool

cuts = false

)

Add emc hits to the list of the rendered objects.

Look up all BEMC tower adc values and render it if (adc > ped + 3 * rms) This function loops over all the softIds, gets the ADC values, pedestals and gain calibrations and calculates the energy. The towers with dc > ped + 3 * rms will be drawn:

• green for E<0.3 GeV,
• blue for 0.3 < E < 1 GeV,
• yellow for 1 < E < 4 GeV (which is approximately the HT threshold for the upsilon trigger at Level-0)
• red for towers above 4 GeV. MCBS.

  Parameters:

  cuts

  - render the towers above 1 GeV only cuts=true cuts=false Courtesy of Manuel Calderon de la Barca Sanchez

void addTracks

(

bool

cuts = false

)

Add tracks to the list of the rendered objects from current MuDst event.

Option cuts is to add the High Pt tracks only, to focus on high pt electron candidates.

Parameters:

cuts

- add High Pt tracks only (tracks with pt > 2 GeV and nSigmaElectron >-0.5 ) MCBS cuts=true cuts=false Courtesy of Manuel Calderon de la Barca Sanchez

		const char *	detectorNames = "TPC,StarBeam"
	)

Main entry point to initialize the primitive "Event Display" and the STAR bfc chain.

Parameters:

	file	- the ROOT file with StEvent
	detectorNames	- the list of the detector names or "0" to draw none

Note:

To start "Event Display" EdMu just invoke:

     ln -s $STAR/StRoot/macros/.rootrc
     root4star EdMu.C

void mae	(	bool	rotation = false,
		bool	doTowerCuts = false,
		bool	doTrackCuts = false,
		int	skipEvent = 205
	)

This mae (AdvanceEvent) function is to search for the next non-empty event and draw it by looping over STAR muDST file (reading the next events from the file).

Parameters:

	rotation	- add the animated rotation defined by "rotation.iv" file ( See also: Inventor Nodes/File Format Quick Reference )
	doTowerCuts	- apply the tower cut (see: addEmcHits(bool cuts )
	doTrackCuts	- apply the track cut (see: addTracks(bool cuts )
	skipEvent	- the number of the events to be skipped on the input file doTowerCuts=true doTrackCuts=true doTowerCuts=false doTrackCuts=true doTowerCuts=true doTrackCuts=false doTowerCuts=false doTrackCuts=false Courtesy of Manuel Calderon de la Barca Sanchez

void mrd	(	bool	doTowerCuts = false,
		bool	doTrackCuts = false,
		bool	clear = true
	)

This mrd (RedrawEvent) function redraws all hits and/or tracks from the current event.

Parameters:

	doTowerCuts	- apply the tower cut (see: mae(bool rotation, bool doTowerCuts, bool doTrackCuts, int skipEvent ) )
	doTrackCuts	- apply the track cut (see: mae(bool rotation, bool doTowerCuts, bool doTrackCuts, int skipEvent ) )
	clear	- flag to mark whether the screen has to be cleaned first (before any new component is added) doTowerCuts=true doTrackCuts=true doTowerCuts=false doTrackCuts=true doTowerCuts=true doTrackCuts=false doTowerCuts=false doTrackCuts=false Courtesy of Manuel Calderon de la Barca Sanchez The event 42752 from Run 8112020 2007Production2 (upsilon) produced by EdMu.C macros
