Very nice.  I guess a comparable plot with ephemeris time would be a
lot noisier and sparser, something like the graphs in the Markowitz
1988 paper.

I wonder if there's some sort of IERS-like official repository for
ephemeris-time data (or, for that matter, other non-Earth-rotation
timescales like the pulsars).  Probably not much call for it, being
mostly of academic interest.

Cheers,
