I found that the diffraction power of ISS had decreased again.

This time, it seems that somebody changed the offset setting for some reason (or maybe it was related to Stefan's ODC activity, see alog 9222). I set it back such that the diffraction power stays at 10%.

H1:PSL-ISS_REFSIGNAL = -1.93 (had been set to be -1.95 by someone on 11th of January)

Note that this value is the same as what I set on this past Friday (see alog 9219)
