18:00: PCT with IS

Since bad weather we work on SW development.

20:00: we attempt a laser propagation but the clouds are too thick.

TN Notes
20141202_041436 Clouds
20141202_061547
20141202_063212
20141202_073001 100 frames with PatCams, clouds are about 4-5km

1:00: We deploy calibration unit

HEXA X Y Z Rx Ry
  -1.01 -2.04 4.28 -489 26

We close the loop on LGS w/o slope offset

TN Notes
20141202_091948 G=0.01

The previous position of the hexapod was considering the Active optics offsets.

HEXA X Y Z Rx Ry
  -1.01 -2.04 4.21 -527 26

We inject a sinusoid with 10Hz period and +/-200nm amplitude on the mirror commands.

Instead of having a single marker on mode # 8 at the beginning of the time history we have it now looping on each Nth frame...

We acquire now snapshots with 16k slopes:

TT removal problem

We generate REC w/o TT removal to see the difference wrt the one generated with TTrm

REC: 20141202_111701 w/o TTrm

4:50: we found a PBL with the subtraction of the TT from the other modes: we were subtracting the Blue pupil TT from all the 3 pupils.
