I performed finer alignment of X arm with ADSs.

Followings are the procedure:

1. X arm lock with both IR and GR.
2. Engage ADSs for PR3 by using GRX PD.
3. Engage ADSs  for PR2 and IMMT2 by using IRX PD.
4. Move ITMX and ETMX so that beam spot on both mirrors are good.

Left figure of fig1 and 2 show the beam spot on ITMX before the earthquake and now, respectively.
Left figure of fig3 and 4 show the beam spot on ETMX before the earthquake and now, respectively.

After the alignment, I recoarded the good OpLev values of IMMT2, PR2, PR3, ITMX, and ETMX.

Followings are the several notes we need to check.
1. IRX beam is not hit to the X arm trans IR camera.
2. GRX beam is shifted on the X arm trans GR camera.
3. We haven't checked the beam on TMSX, so I'm not so sure ADSs work fine (at least, trans power was increased thanks to ADSs, though).
4. IRX and GRX normalized transmission is around 0.7-0.8 now. I'm not so sure this value is due to the bad alignment, bad finesse, or clipping somewhere (GV between BS-IXC, GV between EXC-TMSX, optics on TMSX, and so on).
