Return the errors on the shower direction in the given calorimeter
ICAL : number of the calorimeter. ERRTYP : [1:4] error type : 1 : RPhi or x of shower start point 2 : z or y of shower start point 3 : Theta of shower axis. 3 : Phi of shower axis. CTYP : +ve : Cylindrical detector (RPhi and z given) -ve : Plane detector (x and y given)
