The measurement of the spot positions on the MC mirrors are DONE.
Surprisingly the spot positions are not so different from the ones measured on May.

(some notes)
We used Valera's script senseMCdecenter to estimate the spot positions ( see his entry).
It returns so many EPICS error messages and sometime some measured values were missing. So we had to throw away some of the measurements.
Anyways we gave the resultant ASCII file to Valera's matlab file sensmcass.m to get the actual amount of off-centering in milli-meter.
The attached file is the resultant plot from his matlab code. |
