We agreed to stop at yesterday's meeting. Let it be done.
Well, that makes my life easier.
*But* let's make an effort to get everything in working order nowish, rather than later.
I am taking that to heart on storage and compression.

In case it wasn't clear, the ROACH2 named "pf4" is down again, most likely due to a power problem like before. This means that we are missing 16 antennas(!) as well as 4/32 == 1/8 of the band. The "autoplots" on the blog show the missing parts of the band, but they (and probably the MIRIAD datasets) deceptively show old (recycled) data for the missing antennas.
