The value of IM-Y after connecting the OSEM cables looks unusually large.

• It used to be around -65 µrad in TWR_DAMPED and ALIGNED states (Fig. 1), but
• Now it is almost -3,000 µrad (Fig. 2).
• Other IM degrees of freedom look alright.

It is inconvenient that the oplev was removed. Although such a large displacement is out of the oplev range we could have inpect the position of the beam visually.

I'll just move the IM-Y picomotor to recover the alignment.
