Analysis Task: Doppler Drift

[gadamc]

It's possible to correct the frequency drift due to Earth's rotation. This was previously done using the signalDB database by Graham. He was able to use the date and correct the signal's frequency drift by subtracting out the Earth's velocity at the time of observation.

Need to find his python notebook and create our own. But instead of correcting the numerical value in the signalDB, I'd like to shift the spectrogram along the frequency axis so that we have a spectrogram that has been corrected for drift caused by Earth's velocity.
