We should decide whether we are going to move them soon or once they are in vacuum and in an stable suitable temperature (25 degress for BS/SR2 and 24 degrees for SR3 and SRM). |

See [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=2081| D1302081]] for what each switch does. Four of them are gain stages (24 dB, 12 dB, 6 dB, 3 dB), and three are filters (all 1 Hz zero, 10 Hz pole). Please clarify the switch numbering and functions (switch "1" = circuit board B0 = group 1, filter A1; position 1 = enable?), make a cheat sheet and put a copy in each rack. |
