RVSAO 2.6.4
An IRAF Radial Velocity Package

RVSAO is an IRAF add-on package developed at the Smithsonian Astrophysical Observatory Telescope Data Center to obtain radial velocities from spectra using cross-correlation and emission line fitting techniques.

The latest version is available in IRAF SPP source code at ftp://cfa-ftp.harvard.edu/pub/iraf/rvsao-2.6.4.tar.gz. If you can't get it via ftp, try http://tdc-www.harvard.edu/iraf/rvsao/rvsao-2.6.4.tar.gz. Solaris binary executables for the current version are available via ftp or http
Redhat Linux binary executables for the current version are available via ftp or http
Version 2.0, which is described in a paper published in the August 1998 Publications of the Astronomical Society of the Pacific, is available at http://tdc-www.harvard.edu/iraf/Old/rvsao-2.0.tar.gz.

Tasks in the RVSAO Package

xcsao
extracts redshifts and velocity dispersions using cross correlation methods
emsao
finds redshifts using emission line shifts
contpars
sets parameters for continuum removal in xcsao and emsao
eqwidth
computes equivalent widths for rest-wavelength-specified spectral lines
linespec
creates an artificial spectrum from a list of spectral lines (added in 2.0)
sumspec
sums spectra to create a composite sptectrum (added in 2.0)
contsum
sets parameters for continuum removal in sumspec
bcvcorr
sets barycentric velocity correction for non-standard header parameters
relearn
sets values in the parameter file of the new version of a task from the current values.
