Geometry memo (17Dec2003)

I found some numbers related to the BAT geometry from Craig's report.


BAT_Z of top-of-CZT       =    0.35  [cm]
BAT_Z of top-of-mask-tile =    100.3 [cm]
(The top-of-CZT to top-of-mask-tile distance is 99.95 cm.)

MASKOFFX =     -0.109 +/-      0.003 [cm]
MASKOFFY =      0.078 +/-      0.002 [cm]
MASKOFFZ =      0.105 +/-      0.008 [cm]


These numbers should be included in the simulation coordinate system.
