Similar to what has been done for H1 SUS PR2, H2/H1 SUS ETMY, and H2/H1 SUS ITMY, I've filled out the new(ish) infrastructure for the SEI/SUS signal exchange paths, as described in T1100617. Hence, the channels H1:SUS-MC?_M1_ISIWIT_?_DQ (sampled at 1024 Hz, stored in the frames), represent the motion of the suspension point of the mode cleaner triples in [nm], [projected / derived] from the GS-13s on board their respective HAM ISIs. (Remember, the calibration is only good [i.e. the GS-13s are only integrated] down to 10 mHz, but otherwise should be good out to the Nyquist frequency [assuming the table motion is above the GS13 noise floor]). Further, in preparation for ISC signal exchange, I've installed the 2k to 16k AI filters (see earlier entry for details) in the M3 ISCINF P and Y filter banks. All three SUS's filter files (H1SUSMC?.txt) have been copied over from the "chans" directory /opt/rtcds/lho/h1/chans/ to the userapps repo, /opt/rtcds/userapps/release/sus/h1/filterfiles/ and committed. In addition, I've taken new safe.snaps, and committed them to the appropriate location in the userapps repo, /opt/rtcds/userapps/release/sus/h1/burtfiles/mc?/h1susmc?_safe.snap
