Stelzer and Grill discuss prediction of resolution, based on application of
Heisenberg's uncertainty principle. We discuss different measures of width
of the point spread function (PSF). In our opinion Stelzer and Grill's res
ults should be interpreted in terms of central derivatives of the PSF, rath
er than ill terms of the intensity variance as predicted by the uncertainty
principle. (C) 2001 Published by Elsevier Science B.V.
