Test Mass RMS Watchdogs keep tripping during lockloss

This morning the RMS watchdogs for all of the test masses have been tripping, usually during locklosses at higher ISC_LOCK states. Resetting these requires opening the tripped Quad overview, and setting H1:SUS-*TM*_BIO_L2_UL_RMSRESET to zero, then  back to 1. Since I've had all 4 trip at once, and Verbal_Alarms yells each one at you multiple times, I made an alias in my .bashrc profile to do this. Resetting all of the RMS WDs doesn't seem to effect anything, or disrupt lock, so this alias can be used any time one of these WDs trips. Entering rms_wd in a terminal now sets the WD bit to zero, sleeps for a second, then sets it to 1.

Operators can easily add this to their .bashrc file from a terminal by copy/pasting :

echo 'alias rms_wd="caput H1:SUS-ITMX_BIO_L2_UL_RMSRESET 0 && caput H1:SUS-ITMY_BIO_L2_UL_RMSRESET 0 && caput H1:SUS-ETMY_BIO_L2_UL_RMSRESET 0 && caput H1:SUS-ETMX_BIO_L2_UL_RMSRESET 0 && sleep 1 && caput H1:SUS-ITMX_BIO_L2_UL_RMSRESET 1 && caput H1:SUS-ITMY_BIO_L2_UL_RMSRESET 1 && caput H1:SUS-ETMY_BIO_L2_UL_RMSRESET 1 && caput H1:SUS-ETMX_BIO_L2_UL_RMSRESET 1"' >> .bashrc

You then need to open a new terminal to get the new alias.
