My sincere thanks to all who are responding to my request below.
To be explicit, my question relates to B-factor blurring (+B correction), not
to B-factor sharpening (-B correction).
thanks
Mike

Mike,
you can have a look here (from page 52 and on):

There it is shown that map kurtosis can be used as an optimization
criterion for choosing the best sharpening B.

Dear all
can anyone help me with literatures references to B-factor blurring as a
technique to reveal low resolution features in an electron density map? I have
seen the poster from Andrea Thorn at

but was wondering if there wer
