Attached are the oplev pitch, yaw, and sum trends for the last 7 days for all active H1 optical levers.
Hannah Fair, Stefan Ballmer Some of the ASC and LSC ODC bits that were not in the master bit mask were occasionally triggering mid-lock, without any obvious data degradation. I updated the thresholds listed below. Since the IFO is currently not locked, the SDF is currently very red. THE SDF PROBABLY NEEDS TO BE UPDATED WITH THESE THRESHOLDS. # ASC ezca['ASC-ODC_REFL_A_DC_LT_TH'] = -150 ezca['ASC-ODC_REFL_B_DC_LT_TH'] = -150 ezca['ASC-ODC_REFL_A_DC_GT_TH'] = -1000 ezca['ASC-ODC_REFL_B_DC_GT_TH'] = -1000 ezca['ASC-ODC_REFLA_DC_PIT_LT_TH'] = 0.3 ezca['ASC-ODC_REFLA_DC_YAW_LT_TH'] = 0.3 ezca['ASC-ODC_REFLB_DC_PIT_LT_TH'] = 0.3 ezca['ASC-ODC_REFLB_DC_YAW_LT_TH'] = 0.3 ezca['ASC-ODC_CHARD_PIT_LT_TH'] = 1000 ezca['ASC-ODC_CHARD_YAW_LT_TH'] = 1000 ezca['ASC-ODC_DHARD_PIT_LT_TH'] = 3500 ezca['ASC-ODC_DHARD_YAW_LT_TH'] = 3500 ezca['ASC-ODC_PRC1_PIT_LT_TH'] = 2000 ezca['ASC-ODC_PRC1_YAW_LT_TH'] = 2000 # LSC ezca['LSC-ODC_MICHCTRL_LT_EQ_TH'] = 300000 ezca['LSC-ODC_MICHCTRL_GT_EQ_TH'] = -300000 Old values: ASC-ODC_REFL_A_DC_LT_TH -150.0 ASC-ODC_REFL_B_DC_LT_TH -300.0 ASC-ODC_REFL_A_DC_GT_TH -900.0 ASC-ODC_REFL_B_DC_GT_TH -750.0 ASC-ODC_REFLA_DC_PIT_LT_TH 0.2 ASC-ODC_REFLA_DC_YAW_LT_TH 0.2 ASC-ODC_REFLB_DC_PIT_LT_TH 0.15 ASC-ODC_REFLB_DC_YAW_LT_TH 0.15 ASC-ODC_CHARD_PIT_LT_TH 750.0 ASC-ODC_CHARD_YAW_LT_TH 750.0 ASC-ODC_DHARD_PIT_LT_TH 2500.0 ASC-ODC_DHARD_YAW_LT_TH 2500.0 ASC-ODC_PRC1_PIT_LT_TH 1500.0 ASC-ODC_PRC1_YAW_LT_TH 1500.0 LSC-ODC_MICHCTRL_LT_EQ_TH 150000.0 LSC-ODC_MICHCTRL_GT_EQ_TH -150000.0

/* waffle, random thoughts & meanderings below */ Plots of the reference cavity and pre-modecleaner transmission for the past day. slope of reference cavity transmission 0.27 mW/day slope of pre-modecleaner transmission 110 mW/day slope of QPDY 0.002 microns/day slope of QPDX 0.003 microns/day We should crunch some numbers to see if this is consistent with the beam change out of the pre-modecleaner, The laser output power actually fell over the same time interval. The diffraction average has decreased to suit. Comparison of the cavity spots over the past week can be seen in AlignmentShift.gif.
TITLE: 12/7 DAY Shift: 16:00-00:00UTC (08:00-16:00PDT), all times posted in UTC
STATE of H1: DOWN & HAM2/3 ISIs with Guardian issues being looked at.
Outgoing Operator: Patrick
Quick Summary: useism still elevated (LVEA at 1um/s, but might be trending down slightly if you squint at it). The earthquake band (0.03-0.1Hz band looks like it's finally returned to normal levels at about 14:00utc (6amPST). Hugh is working on HAM2/3 ISI recovery.
IFO has been down for 20+hrs.
O1 day 80
model restarts logged for Sun 06/Dec/2015 No restarts reported
TITLE: 12/7 [OWL Shift]: 08:00-16:00 UTC (00:00-08:00 PDT), all times posted in UTC STATE Of H1: Unlocked SHIFT SUMMARY: Earthquakes tripped most of the watchdogs at the beginning of the shift. Brought everything back except the HAM2 ISI and HAM3 ISI which had guardian user code error messages. Hugh is investigating. SUPPORT: Hugh INCOMING OPERATOR: Corey
Ran into guardian user error code messages for HAM2 and HAM3 ISI. Have done some investigating but don't dare change anything. Suspect it may be related to changes reported in alog 23695. I haven't found a way to get around these.
Noticed SDF differences related to the BS ISI stage 2 GS13. Clicking on LO cleared them.
Guardian user code error after resetting HAM2 ISI watchdog. (see attached screenshot)
Hit LOAD, same error returned.
Same error on HAM3 ISI.
Hitting LOAD on HAM3 ISI does not work either.
No error on HAM6 ISI.
No error on HAM5 ISI.
No error on HAM4 ISI.
No error on ETMX ISI.
ETMY Stage 1 T240 watchdogs tripped in the process of going to isolated.
Everything seems back except for HAM2 ISI and HAM3 ISI. These both have guardian user code error messages. This is preventing the IMC from locking. The ISC_LOCK guardian is stuck in the DOWN state waiting for the IMC.
