High Precision ASC & LSC Round off changes saved in OBSERVE.snaps

First attachment is the ASC changes accepted.  All the ones accepted are gains that have been rounded off to 4 places rather than 10.  I did miss one matrix value (circled) but I've corrected that in the file directly and reloaded that to the FE.  The 23 remaining differences are filters, offsets and matrix changes requiring more scrutiny.

For the LSC, the same applies.  There is one offset difference remaining--see attached.

The one channel remaining in the LSC SDF was H1:PSL-POWER_SCALE_OFFSET, which is changed by the LASER_PWR guardian as it changes the PSL power into the vacuum.  This will be different every lock, so I have un-monitored it in the Observe.snap file.  Also, TJ has changed the guardian to round it to 4 decimal places, which is more than plenty of precision.

Looking right now, everything left in the ASC SDF is stuff that is actively being worked on (SOFT offsets, input matrix for PRC2, etc), so we don't know yet what we'll run with for O2.  These should all stay monitored.

All of the filters in the DC loops were notches that were turned on for a sensing matrix measurement, and should have been turned off.  When I turned the notches off, the diffs went away, so we already had the correct settings accepted.

Thanks for the fine-tuning and details--just what we need for good control--Thanks Jenne--H
