Seismometer Check: MY-SEISX and VAULT-SEISZ are Dead

KeitaK, RobertS, RichardM, JonathanB

We noticed that the seismometer FOMs were showing both dubious H1 range data and strange traces (see page 1).  In the 0.03-0.1 Hz band, signals from the same seismometer but different axes should be at similar levels, but p.1 shows that this is not the case. Running RobertS's PEM test spectra (/hanford2/users/s6/dtt/PEMtestspectra/) on the seismometers showed that the VAULT-SEISZ was running a factor of ~20 lower than the other traces and MY-SEISX seems completely dead.

TIP OF THE DAY:

The projector machines no longer send minute-by-minute screenshots to blue.  To take screenshots on Solaris, I quote from this amazing page:

To Take Screenshot of a Frame

When logged onto the CDE, open a terminal session and run the command as follows:

sunsolaris# xwd -frame > screenshot.xwd

This will prompt you to select a window (the cursor becomes a +), then it will take a picture of the window (as it appears on the screen), the “-frame” options will have it also include the window managers decorative borders, then the file is converted to png.
