IRAF package to obtain radial velocities from spectra

This package obtains radial velocities and velocity dispersions using cross-correlation methods or emission line fits. It consists of several SPP tasks: * XCSAO and PXCSAO: cross-correlate spectra, * EMSAO and PEMSAO: find emission lines in spectra, * BCVCORR: solar system barycentric velocity correction, * SUMSPEC: add and/or modify spectra, * LINESPEC: synthetic emission line templates, * EQWIDTH: equivalent widths of lines in spectra, * WLRANGE: wavelength overlap range for a list of spectra, * LISTSPEC: list pixel, wavelength, delta wavelength, and/or pixel value for spectrum image, * PIX2WL: wavelength at a given pixel in a spectrum, * WL2PIX: pixel at a given wavelength in a spectrum, * VELSET Artificially change the redshift of (log-wavelength) spectra
