Comment to Height adjustment of ITMX (16421)

[Takahashi, Sato, Ikeda]

Measured the relation between number of steps in the stpper motor for FR and the keystone height again. The keystone height of BF was saturated at 6500count smaller than previous measurement. We adjusted the position of the secondary coil again. The recovered height (7100count) was limited by the mechanical stop (see picture).
