Function Documentation

double JCALIBRATE::coincidenceP ( double  E1, double  E2, double  ED, int  M_min, int  M_max  )

inline

Coincidence probability of two PMTs.

Parameters

E1	Expected counts of PMT1 in certain time interval
E2	Expected counts of PMT2 in certain time interval
ED	Expected counts on the rest of the DOM, excluding PMT1 and PMT2
M_min	DOM multiplicity lower limit
M_max	DOM multiplicity higher limit

Returns

Coincidence probability of two PMTs in a certain time interval
