During the down hour, I made shaker injections at HAM1 and IOT2, and made the following site activity injections:

Good news. None of these injections showed up in DARM. Most didn't even show up on the PEM channels (only the electric cart seems to make some noise in HAM6 GS13). The card reader is expected to make a line at ~10Hz, the cleanroom fan is expected to show up any where between 15-30 Hz, and the electric cart on ramp (and bumbs) is expected to show up in the seismometer between 0-100Hz. Attachment #1 - #5 shows DARM spectrogram during the time of different injections. Attachment #6 - #14 shows PEM and HAM6 GS13 (for electric cart on ramp) channels. Every spectrogram is plotted +/-10s before and after the time of the injections. The spectrum of PEM (and GS13) channels at higher frequency can be found here. The Omega scan at the time of each injection can be found here. Look for the scans that were generated on Nov7.
