powerbox.tools Module

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

Functions

angular_average(field, coords, bins[, …]) Average a given field within radial bins.
angular_average_nd(field, coords, bins[, n, …]) Average the first n dimensions of a given field within radial bins.
get_power(deltax, boxlength[, deltax2, N, …]) Calculate the isotropic power spectrum of a given field, or cross-power of two similar fields.
