[AstroPy] got centroid?
Fri Apr 13 10:47:38 CDT 2012
Thanks for the many suggestions, there seem to be quite a few gems among it. For future reference I have put the suggestions on the astropy wiki (very quick and dirty for now), but hopefully that will help us in the long run when looking for these (only seemingly) simple algorithms to center on an object. Feel free to edit and add to it: https://github.com/astropy/astropy/wiki/2ddata_centroid
I also created a root page for 2ddata utilities at : https://github.com/astropy/astropy/wiki/2ddata_util
