... There are two main tasks in the package, XCSAO and EMSAO. XCSAO cross­correlates the Fourier transform of an object's spectrum against the transforms of a set of template spectra with known spectral shifts to obtain a velocity and error. EMSAO finds emission lines in a spectrum and computes the observed centers, getting individual shifts and errors for each line as well as a single velocity combining all of the lines. ... It combines spectra, shifting them to a common redshift. ...
