Based on calibration measurement I have done (elog 11785, 11831), I updated calibration factors of oplevs on medm screen as follows. Not to change loop gain oplev servo, I also changed oplev servo gain.

After making sure that the upper UGFs were properly in place, I saved these settings to the SDF files. Thanks Yutaro!
