Angular coverage in GlueX detector
The geometry of the GlueX detector defines a definite
angular range for photons coming from the target:
The red and blue dotted lines indicate the mininmum and maximum
θ angle subtended by the target for a given position along the
BCAL (in the z-direction). These are used to define an envelope
in θ angle vs. position inside which all photons will reside
in GlueX data.
The following plot shows this envelope along with some points
indicating the angle/positions we will be measuring during the
beam test. The points are not final and come from my sketchy
interpretation of the
Preliminary Run Plan.
This plot was made using this ROOT macro.

Aug. 28th software meeting.
