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.

    Hi Dave et al,

    The still is actually basically at capacity <1TB free on each pot,
    I'd say its about time to stop.


    Cheers,

        Is anybody taking any action on this or are we just going to
        let things run their course as-is?

        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.

        Thanks,
        Dave
