The interferometer was coarsely aligned.
Now spatially overwrapped DRMI and FP arm fringes are visible on the AS camera although the incident beam alignment was done only with PZT2.
All the DC biases were saved so that we can go back to this condition any time.
/***** some health checks *******/
[FINE] IPPOS : it looks okay but the spot on the QPD is a little bit too low by a few mm.
[NOT GOOD] IPANG : maybe hitting a post or something because the spot is vertically split into two. The spot is too low.
[FINE] POX/POY/POP : they all are coming out. POP is visible with an IR viewer.
[FINE] REFL : no clipping but the beam looks a little bit too low relative to the CCD camera.
[FINE] AS : no clipping and the spot position on the AS camera looks fine.
[FINE] Green beams : both X and Y beams are successfully landing onto the PST table without no clipping.
[FINE] Suspensions : all of them are reasonably quiet without the oplevs, which is good.
