Edgard,

I took the ST2 X to M0 L and P transfer functions needed to do the L and P simultaneous feedforward (T1800301). 

To do so I used the dtt template files located in the svn, with just enough modification to export the relevant quantities:    

/ligo/svncommon/SusSVN/sus/trunk/QUAD/H1/ITMX/Common/Data/2018-08-14_H1SUSITMX_M0_ISIFF_FilterDesign_ISIST2L_2_L3P.xml
/ligo/svncommon/SusSVN/sus/trunk/QUAD/H1/ETMX/Common/Data/2018-08-14_H1SUSETMX_M0_ISIFF_FilterDesign_ISIST2L_2_L3P.xml

The results for the transfer functions are shown in the first two attachments.

The third attachment was my attempt to make a measurement of M0P to M0 L,P, for ITMX immediately after that,  but there is this strange feature around the lowest resonance that drops my confidence on this measurement by a bit.

I suspect that, since I turned off the M0 damping filters, I rung up the longitudinal modes of the quad. And what I am seeing here, is a lot of motion at those frequencies unrelated to M0P drive.

In any case, it bothered me enough to stop there for those two suspensions.
