Paper Abstract

The Sloan Digital Sky Survey(SDSS) is a redshift factory producing more than 5000 spectra a night when conditions allow. In order not to fall behind the data acquisition, highly automated and accurate spectral reduction pipelines are needed to process the data. Also the varied nature of SDSS target selection: the main galaxy sample, the large red galaxy sample, the QSO sample, stellar targets, and serendipitous objects; requires the pipeline to be adept at handling the full range of astronomical spectra, from a redshift of 0 out to a redshift of 6. The SDSS spectra are of exceptionally high quality, allowing the pipeline not only to determine redshifts and broadly classify the spectra, but also measure line parameters, calculate spectral indices, velocity dispersions etc. The purpose of this summary is to give an overview of the workings of the pipeline and its outputs, and give some guidance in using those outputs.
