negative model power

[nicholebarry]

Looking at some old PS, I've stumbled upon negative model powers. What is particularly strange is that this is showing up in just one of the polarizations. These PS were made from the full Beardsley thesis list and with the modified gridding kernel, and were made <6 months ago.

In the plot, you can see the blue XX model is below the plot range in-between the coarse bands. I checked the power, and they are in fact negative. I'll keep looking into this. This is could also be a FHD issue...or even a non-issue, given that the data were analysed a while ago.

I also found some negative model power when I hacked in some baselines that did not move in time, but ought to have since the data is phased. Maybe something is up with the phasing of that data?
