We measured the MC spot positions after re-aligning the MC. The spot positions are listed below:
spot positions in mm (MC1,2,3 pit MC1,2,3 yaw):
3.9073 6.6754 2.8591 -7.6985 -0.9492 7.0423
1) In the directory /opt/rtcds/caltech/c1/scripts/ASS/MC we have the following scripts
a) mcassUp: This sets up the MCASS lockins to excite each of the MC mirrors at a different frequency
b) mcassOn: This sets the MCASS output matrix to actually send the excitation signals to the mirrors
c) senseMCdecenter: This sequentially introduces a 10% offset into the coil gains of each mirror degree of freedom. It also sends the lockin output data to the screen.
d) sensemcass.m : This is a matlab file which digests the data gathered by the senseMCdecenter script to print a couple of plots and compute the spot positions.
e) MCASS_StripTool.stp: This is a set-up file for the StripTool which allows us to see the MCASS-lockin_outputs. It is nice to see the action of senseMCdecenter script at work.
2) So the series of commands to use are
a) ./StripTool <-- MCASS_StripTool.stp
d) ./senseMCdecenter | tee Output_file
g) matlab <-- sensemcass.m <---- Output_file
