Currently the top of the thermal blanket is modeled as 32.7 mm thick. All dimensions are available from the RM, for example GR v9r1 https://www.slac.stanford.edu/www-glast-dev/cgi/xmlParams?sessionId=1470ea98f085564ae73de7ac067b43fa&cpId=6219#NADDimPrim
From which we see that the top is 1756.34 mm x 1756.34 mm x 32.7 mm
Constants for the sides:
NADBlanketSideY_l | 1756.34 mm | length in long |
NADBlanketSideX_l | 1690.94 mm | length in long (Y) dimension of X-sides of blanket, shorter than Y-sides because Y-sides cover corners |
NADBlanketSideZ | 1075.11 mm | height of a side piece of the blanket: approx. height of ACD side tiles + height of cal |
