Guy (and list), in a couple of super-resolution talks I've attended they were using 0.51 instead of 0.61 for the constant. Do you know the rationale behind this?
Thanks, Brian

You are right, it has been totally drowned out!
The Airy unit is defined by the size of the Airy disk, that is the size
of the disk representing the image of a point object. Airy was an
astronomer and thus derived it by reference to stars (which, though
huge, are so far away that they appear as point objects). John Strutt,
Lord Rayleigh, proposed a general resolution criterion that two objects
can be considered resolved if the maximum of one Airy disk lies on the
first minimum of the other. This criterion, the radius of the central
disk (ignoring surrounding haloes) is given by r = 0.61 lambda /
NA, where lambda is the wavelength of the light being used.

And I hate to point this out, but the question I originally asked
(concerning the definition of Airy Units) has been drowned out by all
the
commentary about the "Out of Office autoreply" that my initial email
generated.
If nobody has an answer to the question, no worries, but I'd hate to see
the
topic get lost under the weight of discussion of listserv function.
