Hi all, I have a small variogram module I'd like to make available. All it does is compute directional variograms on the sphere. It has a little bit of fortran code. Questions: - Should I be making an effort to interface with any code in the stats module? - The output is essentially a list of bar-graph components. On my computer, I have a function that uses matplotlib to actually plot the variograms. Should I wrap the function in a try block, so that it will be available if 'from pylab import *' works, or get rid of it? - When making directional variograms, the code bins by bearing angle rather than by atan2(delta long, delta lat). Is this the best way to do it? The bearing angle seems to make more sense but - bearing(a,b) isn't necesarily equal to pi + bearing(b,a), so the same pair can go in two different bins, and - the bins tend to look strange on a cylindrical projection if the points are far apart. I haven't been able to find much guidance in the literature. - How should I package the module, and how can I get it to someone who can put it in the repository? Thanks, Anand
