Hi Brian,

I used binaries, that's a stupid fault, I should try recompiling.

There are several aspects that seriously influence deconvolution accuracy and
PSF generation speed. I commonly acquire z-stacks with depth up to 10mkm
using NA 1.2 (WI, live cells or moviol embedding) or NA 1.4 (OI, Apathy's
medium or pure glycerin embedding). I do not remember the proof (they can
easily be verified experimentally) , but G&L model is suitable if:
1. Low-aperture (<0.5) objective is used
or
2. NA<1 and imaging depth is lower than 1-2 mkm
or
3. any NA, no immersion RI mismatch and imaging depth <3 mkm

The factors that influence PSF generation time by COSM are, don't know why
so seriously
- tube length. Nikon OTL is 200, default - Zeiss 170 - is faster
- coverglass thickness (#1.5 generate faster than #0)

Thanks for oversampling factor hint, I'll use it.

Best,
Sergey
