BCAL Angular Coverage
From GlueXWiki
Correlation between theta angles and impact positions on the BCAL, for the production/physics runs of GlueX. These were calculated based on the current GlueX drawings and translated to the -200cm to +200cm (z=0cm is the middle of the BCAL Module-1) reference frame used during the 2006 Test Beam in Hall-B.
theta Z (degrees) (cm) -------------- 50 -112 40 -102 30 -54 20 +10 19 +22 18 +33 17 +46 16 +60 15 +75 14 +93 13 +115 12 +138 11 +167 10 +201 (unphysical, beyond BCAL edge and into FCAL acceptance)
