H1 ISI CPS Sensor Noise Spectra Weekly, FAMIS 12876

I ran the scripts for this FAMIS task on Dec. 2, while the site was still experiencing high useism.  The xterm window did not produce a list of any sensors being over threshold, and by eye it looks like there might be some sensors on BS that had (or have) elevated noise.

I also noticed peaks at around 6.9Hz, 7.6Hz, and 8.0Hz that were not in the spectra from Nov. 18th, in ITMY, HAM5, and HAM6.

In all attachments with two side-by-side plots, the current spectra is on the left, and the spectra on the right is from alog 53315, Nov. 18th.

I checked the current spectra against the Nov. 25th plots, alog 53473, and the changes noted above are new since those spectra.
