No, I ran the ADEV in Stable32 without removing drift. My understanding
is that linear drift shouldn't affect the calculation. I was also a
little concerned whether drift removal would work very well given that
both Cesiums had periods where the offset changed for quite a long
period (CS1 near the end of the data, CS2 at the beginning) and I wasn't
sure what impact that might have.

I'll be happy to ship the data to anyone who's interested. Each file is
about 600kb before compression, and it compresses well.
