RVSNUpy: A Python Package for Spectroscopic Redshift Measurement Based on Cross Correlation
We introduce RVSNUpy, a new Python package designed to measure spectroscopic redshifts. Based on inverse-variance-weighted cross correlation, RVSNUpy determines redshifts by comparing observed spectra with various rest-frame template spectra. We…
