Quick bugfix to SUS QUAD L3 LOCK Filter Bank MEDM
J. Kissel
IIET Ticket 8193

A decade ago, Rana put in the above IIET ticket calling out that we made the QUAD's custom L3 LOCK bank before the RCG was able to ramp the offset, and/or before the ramping of the offset got highlighted yellow during ramping like the gain typically does. I've fixed this issue this morning by grabbing the latest auto-generated versions of these filter banks from

    /opt/rtcds/lho/h1/medm/h1susetmx/
        H1SUSETMX_ETMX_L3_LOCK_BIAS.adl
        H1SUSETMX_ETMX_L3_LOCK_L.adl
        H1SUSETMX_ETMX_L3_LOCK_P.adl
        H1SUSETMX_ETMX_L3_LOCK_Y.adl

and hand copied the filter medm guts over to the

    /opt/rtcds/userapps/release/sus/common/medm/quad/
       SUS_CUST_QUAD_L3_LOCK.adl
then search and replaced "H1:SUS-ETMX" with the macros "$(IFO):SUS-$(OPTIC)" in order to make it sufficiently generic for all QUADs and both sites to use. Also, while there, I took the extra effort to remove all the old "Online Detchar Channels," or ODC channels that were removed and/or deprecated after O2. The updated screen is committed to the userapps svn as of rev 27162.

Attached is the screenshot showing the BIAS offset being ramped as a test (this was the original motivation for the ticket).

This closes the ticket!
