OMC length sensing noise in DARM

At the beginning of the maintanance window, at about 16:27:20 UTC I doubled the OMC LSC dither amplitude by a factor of two while reducing the OMC LSC-I gain by the same factor so the overall OMC LSC control bandwidth doesn't change. I wanted to repeat low/high comparison but IFO broke lock (not because of this test).

Anyway, just for this one test, I don't see any difference.

The changes were reverted back.
