There are two columns with very little data.
1) experimental resolution
2) upper limit on v(aether).
After your review of MMX and Miller data, recently,
are you in a position to complete this missing summary
level information for these gas mode interferometer
experiments?
For MMX and Miller, yes. I have not looked at the others. I have no idea
when I'll get time to edit the page, however.
What figures would you be placing against
MMX and Miller, with any qualifications, etc?
From your perspective, as far as I understand it, you'd be
asserting that the 1) experimental resolution is in fact the
ALL-TELLING parameter (or one of a series of) by which
an experimental result might be classified as a "null result".
To a certain extent, you have convinced me of the consistency
of such an approach, and I am interested to learn what your
prior research has derived for these figures. You have posted
some detail for MMX I recall (which I may yet find in the archives)
but not yet for Miller.
I have searched high and low for reference to this information
(as one might have thought it should be pre-calculated
somewhere considering its [retrospective] importance) but
to no avail.

QUOTE for the DAY:
============[MMX 1887]============================
....[trim discussion of setup]...
The paths being now approximately equal, the two images
of the source of light or of some well defined object placed
in front of the condensing lens, were made to coincide, the
telescope now adjusted for distinct vision of the expected
interference bands, and the sodium light was substituted
for white light, when the interference bands appeared.
These were now made as clear as possible by adjusting the
mirror; then white light was restored, the screw altering
the length of path was very slowly moved (one turn of a
screw of one hundred threads to the inch altering the path
nearly 1000 wavelengths) till the colored interference
fringes reappeared in white light.
These were now given a convenient width and position, and
the apparatus was ready for observation. The observations
were conducted as follows:
Around the cast-iron trough were sixteen equidistant marks.
The apparatus was revolved very slowly (one turn in six
minutes) and after a few minutes the cross wire of the
micrometer was set on the clearest of the interference
fringes at the instant of passing one of the marks. The
motion was so slow that this could be done readily and
accurately. The readings of the screw-head on the
micrometer was noted, and a very slight and gradual impulse
was given to keep up the motion of the stone; on passing
the second mark, the same process repeated, and this was
continued until the apparatus had completed six revolutions.
....[trim]...
The following tables give the means of the six readings; the
first, for observations made near noon, the second, those near
six o'clock in the evening. The readings are divisions of the
screw-heads. The width of the fringes varied from 40 to 60
divisions, the mean value being near 50, so that one division
means 0.02 wave-length. The rotation in the observations at
noon was contrary to, and in the evening observations, with,
that of the hands of a watch.

Well, it IS the parameter that matters. If you obtain a result
like 2 +/- 3, then any number between -1 and 5 is consistent with
that result. Convincing anyone to accept a result like that as
anything but null for a michelson-moreley type experiment would
be difficult at best.
To a certain extent, you have convinced me of the consistency

If you aren't convinced, you have no business discussing experimental
data.
