[ Takahashi(NAOJ), Okutomi, T.Miyamoto ]

We started to characterize of cryo-payload.

at first, we checked the condition of type-A suspension.

As check item, we measured the transfer function.

In particular, IP stage was strange.

We was not able to measure the transfer function of IP-GAS to IP-GAS.

previously, Okutomi-san measured data (2018/01/09):  https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=7671
