It seems that dataview.raspberryshake.org has changed. It doesn’t seem to work on my newer browser, but does on my old one, that’s a separate issue.
I see there’s a new button, “toggle demeaning.” It appears to allow things to display my shake’s average motion as 0 m/s. Nice to see that crustal deformation is not as high as it appeared before. 
That’s a separate issue too.
I was looking at something today and switched to the spectrogram view and was greeted with a scale that runs from -25 Hz to +25 Hz. I have an EE degree, so negative frequencies don’t freak me out, but after looking at it for a bit it just didn’t look right and wasn’t as symmetric as I expected.
Then it dawned on me - the web app had demeaning off and had shifted the normal 0-50 Hz to have a 0 center frequency! Turning demeaning on (EEs have to deal with negative logic all the time too) restored the old, sensible display.
Oops. Cute, but please fix!
