[time-nuts] ADEV vs. OADEV

[Magnus Danielson]

Hi!

I have been quite surprised to see the abbreviation OADEV appear. I 
assume that this means Overlapped Allan Deviation, but this is confusing 
since the Allan Deviation estimates already is overlapping. However, I 
have seen that some use a non-overlapping estimator, but this type of 
estimator has an unwanted filtering effect and should not be used.

If a distinction between these ADEV estimators should be used, then the 
standard (overlapping) estimator should continue to be called ADEV and 
the non-overlapping (back-to-back) could be called NOADEV ór whatever...

I have done a fair amount of digging around many sources around ADEV and 
friends so I think I got it right.

Unless someone can give a meaningful explanation and I really expect a 
good article detailing the difference and benefits...

Cheers,
Magnus
