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? Pavel On 5/9/15 2:15 PM, Peter Zwart wrote:

Hi Graeme,

I can clean this up, the monster is an overkill. Can we chat offline tomorrow / Monday?

Hi Folks

Digging around some more found the test for the Zernike stuff, now have

from __future__ import division

def tst_nss_spherical_harmonics(): from scitbx import math from scitbx.array_family import flex N=50 M=20 lfg = math.log_factorial_generator(N) nsssphe = math.nss_spherical_harmonics(M+5,50000,lfg)

l = 2 m = 1 t = 1 p = 1

print nsssphe.spherical_harmonic(2, 1, 1, 1)

tst_nss_spherical_harmonics()

Not clear what a log factorial generator is, but seems to work

if I am only caring about small integer l for Ylm do I need to have the big numbers above?

Thanks Graeme
