NOTE: the following data have been acquired with the disturbance created the 13 Nov in Arcetri. These files are just a renamed version of the ones used with RR (double pass of light on M2) so they are missing a factor 2 in amplitude when used with ARGOS calibration unit (single pass of light on M2).

We try to close the pupil loop but the system crashes because we loose the bottom right part of the mirror (as seen from the
FastGUI)
We recover the system without disturb, low gain:

New define a new subaperture set removing the bottom right edge of the red pupil that is quite vignetted when the calibration unit is in use. The Subap removal is done automatically setting the threshold value to 0.3 of the pupil median flux value.
SUBAPERTURE SET: 20141126_192200, slope computation algorithm is
CoG
We rise the diodes flux and we record a new IM for the new subaperture set

Measuring on the fly the slope RMS we get the following values: 62nm rms in OL, 23 nm rms with G=0.4 to all modes, 33nm rms with G=0.1
