I'm not totally sure why it looks like this, but I suspect it's partially to blame for the increased BLA loss we're seeing.

The small FLIR unit has a only low resolution thermal sensor, not that of an optical sensor.

Entry Makers: victorcBody: Cavity tripped FSD three times in a row. P1 faults. Not sure the exact issue. Tried an OLT and it hasn't tripped since.

Steered closer to zero, as well as balanced the xC dipole to energy. xC FFB reengaged without problem.

Comparing FOpts a little under a day apart, it looks like large differences in dispersion surface between C and D lasers. Differences start as early as 1L, becoming significant by 2S -> 2A. We don't have a good comparison of FOpts between C and D since the C pass change so differences are a bit difficult to track down. Either way, vertical dispersion is well out of spec by 2R.

Working on finding what is causing the issue, it may be coming from early on in the machine. Loss on IDX is different than it was yesterday. At the moment we will try to find the cause of the loss rather than do another BLA cal.
