powerbox.tools

A set of tools for dealing with structured boxes, such as those output by powerbox. Tools include those for averaging a field isotropically, and generating the isotropic power spectrum.

Functions

angular_average(field, coords, bins[, …])	Perform a radial histogram – averaging within radial bins – of a field.
angular_average_nd(field, coords, bins[, n, …])	Take an ND box, and perform a radial average over the first n dimensions.
get_power(deltax, boxlength[, deltax2, N, …])	Calculate the isotropic power spectrum of a given field.
