DQ Shift: Thursday 4th - Sunday 7th May

The full DQ shift report can be found on the DetChar wiki. Here are the highlights:

*) 77% observing time over the DQ shift. In the longer locks it's really noticeable to range degrading, particularly on Thursday and Sunday.
*) Locks on Thursday going in to Friday seem to have a higher rate of blip glitches compared to previous and preceding days. Not sure of the cause - will investigate more
*) ETMX/Y oplevs are still glitching a lot - they're the main round winners according to hveto Friday through Sunday.
*) From Friday onwards there are a lot of overflows in the IOP SUS EY model and near continuous software situations in NGN-CS_CBRS_RY_PZT1/2_CTRL. I don't see any particular way these are causing problems with the range / glitches (unless it's very quiet).
