Subject: Y arm ASS fixed 

The servos of C1ASS for the Y arm and the beam axis alignments were fixed.

Now we can correctly run the Y arm ASS from the C1IFO_CONFIGURE window as usual.

The sign of some control gains had been flipped for some reasons, so I changed them to the correct signs.

 

Next : Health-check for the X arm ASS, the loss measurements.

Quote from #5062

I tried using C1ASS to align the incident beam and suspensions on the Y arm, but it didn't work.
