A few data points for BRS

A few spectra regarding BRS at EX. The red traces are from today at about 11:00am local (when I'm pretty sure people were working at EX, I wanted something noisy), blue traces are from ~3:00 last night (quiet), green are from the night of the 10th this month, after Krishna did his check up and recuperation of the BRS (alog 16434), though the peak at 8mhz  suggests the BRS was rung up.  Solid traces are the STS, dashed lines are the BRS signal for each measurement (see alog 14047 regarding calibrations for these spectra). Krishna was worried that the BRS software may have crashed (as it does every ~2 weeks), but no one has had time to check it out in person today.
