| Description: | When the signals are very low, a regular feature can be seen in the data. It begins on
the hour, and lasts for ~20 minutes. This feature is a rise in the signal of 0.25 to 0.33
mV. It is small even when compared with the NFOV's typically small signals.
My initial hunch is the NFOV is located next to or nearby equipment that
operates/broadcasts/etc beginning on the hour, and lasting for ~20 minutes.
Looking (very closely) back at the previous deployment, this regular signal bump is also
evident, so it seems the equipment contaminating the NFOV is part of the AMF1, and not
unique to this deployment. 20111222 is a good example of the issue. |
