J. Kissel, for H. Radkins, M. Ross, and J. Warner.

Thanks to the work of the seismic team today (see LHO aLOG 51417 and LHO aLOG 51421), after watching the BRS X signal for a few hours, we've found it to be glitch free -- so we've resumed including it in the ETMX ISI's sensor correction leading up to and including the current observation ready segment, and plan to continue to include it until further notice. 

Attached is a live stream of the last 10000 seconds of BRS X signal. It is glitch free. The "DC" value is still evolving with a very long time-constant which we suspect to be the normal ~12 hour thermal recovery time-constant after opening the thermal enclosure, unraveling some of the additional BRS vacuum chamber thermal shielding, etc. during today's deBUGging.

This should close out FRS Ticket 13417.
