noise_region_uncertainty

specutils.manipulation.noise_region_uncertainty(spectrum, spectral_region, noise_func=<function std>)

Generates a new spectrum with an uncertainty from the noise in a particular region of the spectrum.

Parameters:

spectrum: `~specutils.spectra.Spectrum1D

The spectrum to which we want to set the uncertainty.

spectral_region: `~specutils.spectra.SpectralRegion`

The region to use to calculate the standard deviation.

noise_func: callable

A function which takes the flux in the spectral_region and yields a single value for the noise to use in the result spectrum.
