Hugh did a lot of work over the last few weeks diagnosing the ITMX ISI, with respect to it tripping earlier than the other platforms during an earthquake. His fix last week seems to have worked, at least for the earthquake Friday. First 2 attached plots are the ST1 WD Triggers (the ISI has tripped when the trigger /= 0, first plot shows the triggers separately, second is all on the same plot) , and ITMX, ITMY and ETMX all trip at roughly the same time. ETMY and the BS trip several minutes later, but they were in different configurations (BS is always Isolated_Damped, ETMY had it's sensor correction turned off). This was a large earthquake that came up quickly (third plot shows ETMY Z STS 30-100 mhz BLRMS and ITMX WD trigger) , but for now it looks like ITMX is behaving like the other platforms.
