SEI_DIFF Back To CORNER_DIFF_CPS and Not Monitoring DIFF Control Bit

Earlier today, decided to turn SEI_DIFF back "ON" by taking it to an operational CORNER_DIFF_CPS state.  (it was turned OFF yesterday due to high microseism).  This brought up a SDF Diff for the DIFF CONTROL BIT (see 1st attachement).  Since this is a new guardian node which will change with microseism, I went ahead and NOT MONITORED this channel.  Probably too early to tell and also hard to tell since microseism is also inching down, but 2nd attachement is a look of glitches via DMT OMEGA (where the microseism shelf noise/glitches is in the 20-35Hz region).

Wanted to also see how we've been locking with microseism, H1 range,  SEI_DIFF states (200 is FULL & 190 is CORNER), ISI CONTROL BIT channel over the last ~7 days (see 3rd attachment)
