Comparing our LHO data attached, from March 30th when Dan changed the OM2 PSAMS (alog 68270) to Wen's LLO plots here, from his slower overnight tests (LLO alog64714).

For a similar OM2 temperature change of ~20degrees, we see:

• A 1% change in KAPPA_C - similar to LLO
• No obvious H1 range change - LLO's changes 15MPc
• We didn't have our ADF on the any time we were changing OM2 TSAMS
• SQZ BLRMs at 1.7kHz (#5) is constant - LLO's changes 2dB.
  • A plot of all our SQZ BLRMS shows #6 (4.6kHz) gets slightly worse and #4 (750Hz) slightly better...?! (SQZ angle was adjusted during that time but 5deg shouldn't make a large difference.)

Could repeat this test with slower steps overnight with ADF on ~100Hz and constant SQZ settings.

Dan, Andrew and Derek also note some glitches during the last OM2 TSAMS test at LHO and that the alignment was changing a lot (alog 68270).
