<p class="MsoNormal">Alright, let's try this again, forward 8 years (2000), Angert et al, zero-loss (no inelastic scattering) and of course in a practical sense the ice thickness and size of the aperture DO influence the contrast (for the same defocus or in-focus
image), but I do not recall other papers where it was quantified methodically (thoroughly)...<o:p></o:p></p>
