Yesterday, Sheila moved ZM3 in steps of +10urad in PIT on the sliders (towards the diorection we know we need to be for SQZT7 light). She then compensated with FC1 and FC2 to maximize FC green flashes each time. And then measured the amount ZM3 needed to be moved to get light on SQZT7, ZM3 needed to be moved less each time to get light on SQZT7 IR PD (good) however, the flashes could not be brought back to thier maximum (bad). Plot attached.

Today, I moved ZM3 in steps of -10urad in PIT on the sliders (away from the diorection we know we need to be for SQZT7 light). Then compensated with FC1 and FC2 to maximize FC green flashes each time. And then measured the amount ZM3 needed to be moved to get light on SQZT7, ZM3 needed to be moved slightly more each time to get light on SQZT7 IR PD (bad), but the flashes could be brought back to thier maximum and mayeb even got slighly better (good).
