deresolv

Purpose

Changes high resolution spectra to low resolution.

Synopsis

lrspec = deresolv(hrspec,a)

Description

DERESOLV uses a FFT to convolve spectra with a resolution function to make it appear as if it had been taken on a lower resolution instrument. Inputs are the high resolution spectra to be de-resolved hrspec and the number of channels to convolve them over a.

The output is the estimate of the lower resolution spectra lrspec.

deresolv is useful for standardizing two instruments of different resolution. It can also be used to smooth spectra.
