Function Documentation

BuildDetector()

Smear::Detector BuildDetector

(

)

Smearing parameterisations for the eSTAR detector.

Based on parameterisations given in Zhangbu Xu's talk here (slide 5): https://wiki.bnl.gov/conferences/index.php/January_2014 This includes momentum and energy resolutions, but no particle identification.

Note: you must gSystem->Load("libeicsmear") BEFORE loading this script, as ROOT needs to understand what a Smear::Detector is.

etaToTheta()

double etaToTheta

(

double

eta

)

Helper function to convert eta to theta (radians)

Detector acceptances require theta, not eta

Smear::Acceptance::Zone zoneEta	(	double	etamin,
		double	etamax
	)

Helper function producing a zone in eta.
