SpectRes: Simple Spectral Resampling

SpectRes is a Python function which efficiently resamples spectra and their associated uncertainties onto an arbitrary wavelength grid. The function works with any grid of wavelength values, including non-uniform sampling, and preserves the integrated flux. This may be of use for binning data to increase the signal to noise ratio, obtaining synthetic photometry, or resampling model spectra to match the sampling of observational data.

Installation

SpectRes can be installed using pip

pip install spectres
