Temperature and temperature distribution histories and/or statistics for the air inside the dome, as well as for the various components of the system: structure, glass, camera skin.
Operational Parameters:
we expect the M1M3 thermal control system to control the thermal gradients in the M1M3 mirror substrate to within 0.4C in x and y lateral directions, and 0.1C in radial and axial directions. (05/2009)
