Yesterday I did a pass of RFI removal with the current algorithm, and I scored 100K pixels. "RFI removal: standard" now uses the current algorithm.

If you look at the top-scoring barycentric multiplets, you'll see that they consist of two types of features:

1) Drifting RFI with a high drift rate, above the limit that we were using. Interestingly, this includes some Gaussians as well as spikes. We can probably tweak parameters to get rid of this.

2) Period bursts of clusters of spikes. We're going to have to take a close look at this; it's not immediately obvious that it's RFI.

Thanks for the update. When you and Eric get your heads together, it's a pretty good combination, and I'm sure you'll tweak it as necessary.

Working with Eric is a blast. He does the math, I write the code.

No need to bite either for any of such (or possibly it should be that of making fun with instead).
