Mirror reflattening

reflattened mirror using the optical interaction matrix data in meas/flat/2009_08_10

print, opt_int_mat_reduce(600,/MULT,NMEAS=5)

peak force: -0.44N in the inner ring

residual rms (2*surface): 36nm rms (tip-tilt,focus,coma removed).

Forces are too high!

Flattening with less modes to reduce the forces.

20:00 system restart

several failures during startup (set&flat procedure). in the end the shell was set using the GUI set_flat command, then the ICC was reset using

That will be the flattening configuration for the following measurements
