Binning data

While ExoIris aims to be fast enough that binning of data is not usually necessary, we still may want to do it every now or then. For this, ExoIris provides the Binning and CompoundBinning classes that can be used to define complex, non-regular binning geometries. These can be used to bin spectroscopic light curve data sets stored as TSData objects using its bin_wavelength method.

Binning

The Binning class creates a homogeneous binning from xmin to xmax based on either a given number of bins (nb), bin width (bw), or resolving power (r). Giving a number of bins divides the range into nb equally wide bins while giving the bin width divides the range into bins that are as close to bw as possible. In both cases, the bin widths will be constant. Giving the resolving power, the range will be divided into bins with widths following the x/dx relation.

Binning(xmin, xmax[, nb, bw, r])	Class representing a homogeneous binning within a given range.
Binning.bins	A (nb, 2) array of left and right bin edge values.

CompoundBinning

The CompoundBinning class creates a heterogeneous binning by combining several Binning objects.

CompoundBinning(binnings)

A class representing complex heterogeneous binning.
