Comment to Health check for ITMY (28407)

Attached figures show the TF measurement results of ITMY.
Some GAS TFs changed but there seems no serious problem.
GAS TFs are better to be checked by Takahashi-san.

Followings are some note:
1. IP_IDAMP_L and IP_IDAMP_T are now mixed signals of geophone and accelerometer while they were just geophone signals when reference TFs were measured.
2. I have no idea on gain increase of F0 and F1 at high frequency.
