DetectorEdgeMM (
        self,
        ang,
        margin=0,
        )

A pointer to a vector on the edge of the detector.

parameters:

ang

the angular position on the edge of the detector. The angle 0 is pointing to the right (positive y, positive theta) side of the detector, pi/2 points up (positive z), angle pi is pointing to the left (negative y, negative theta) and 3/2*pi is pointing down (negative z).

margin

how far to stay away from the real edge of the detector.

Hit (
        self,
        mmx,
        mmy,
        margin=0,
        )

Check whether the position mmx,mmy falls on the active area of the detector.

This can either be called with floating point values mmx and mmy or with Numeric arrays. In the former case the return value is either 1 or 0, in the latter it is a similarly shaped array of 0's and 1's.
