Eric Korpela recently reported an anomaly that turned out to be a bug in how I was building indices. I fixed this and re-ran the pipeline, and the multiplet/pixel results are now online.

But waterfall plots aren't working properly. I haven't finished moving the signal data from Hannover back to Berkeley, in part because the machine we're storing it on (jansky) has a flaky network interface card.

These data transfers are now a bottleneck. I can run the pipeline in about a day, but it takes many days to transfer the signals. I'm using rsync over ssh. I talked with Matt Lebofsky, who says he knows how to speed things up by a significant factor. I'll be looking into those once the jansky hardware situation is fixed.
