Why move discussion off line? I see myself using this sometime in
future, so I'd like to know quality/usability-status of the code
being out there. My opinion is binary in this respect: if it is out
there I expect it it works and I can trust it. If it is it not
otherwise ..... - please tell me why I should not trust your
contribution to the open source library? <br>

Digging around some more found the test for the Zernike

def tst_nss_spherical_harmonics():<br>
� from scitbx import math<br>

� print nsssphe.spherical_harmonic(2, 1, 1, 1)<br>
<br>
tst_nss_spherical_harmonics()<br>
<br>
Not clear what a log factorial generator is, but seems to
work<br>
<br>
if I am only caring about small integer l for Ylm do I need
to have the big numbers above?<br>
<br>
Thanks Graeme<br>
