Preliminary Alignment

M3: -1150 750 0 Sel = 38.85

hexapod: -2 0 1 -150 -450 0

Shell set successfully

the 4D image is highly saturated, although the gain is 1 and the exposure time is the minimum. communication problem with the camera? let's check the test/ref ratio

Repair of Siggen cable

after the repair the unit was set and rip many times for tests. we also tried the time history. all successfull

Preliminary flat

adding some arbitrary astigmatism

4D sampling changed to 1 (1000x1000) to increase the capture range and measure large fringes density.

Test of automatic flat
