The Smithsonian Astrophysical Observatory Telescope Data Center creates and maintains software to process and archive data from optical telescopes at the Whipple Observatory and MMT Observatory on Mt. Hopkins in Arizona. The software is freely distributed and documented online.


A variety of tasks for reducing multifiber spectra from the Hectospec and Hectochelle spectrographs on the MMT.


Tasks used to find radial velocities and manipulate spectra


Various utilities for dealing with data


Perform singular value decomposition on stacked spectra and remove the weighted eigenvectors which are found from other spectra.
