Hi Stephen, These look great and very well-documented. I'd say put them in math_utils for sure. Would it be possible to change the function names from CaptialAtEachWordStart to lowercase_and_underlined, to follow PEP-8? thanks, Matt On Fri, Aug 20, 2010 at 4:07 PM, Stephen Skory <stephenskory@yahoo.com> wrote:

Hi all,

I've just written functions to compute velocities of things in various ways, primarily for halos. For example, one could use these to calculate the circular velocity curve of a halo very easily. I do this by rotating and translating the coordinates to make the velocity calculations very easy. I am not done with this stuff, I need to write some code such that the vector output can be de-rotated back into the original physical coordinates. For now it outputs velocities as 1D speeds, which is good enough for me right now. Anyway, what I'm asking is, where do we think is the best place to sick this in terms of the yt directory hierarchy? I have a file named 'math_utils.py' which might be appropriate for this. This will go in yt-dev for the near future. Ideas?

The heavily documented code:
