Abstract
The DEEP2/DEIMOS redshift survey, which will begin observing in the Spring of 2002, will gather high quality spectra on ~60000 galaxies in order to study the evolution of the properties and large scale clustering of galaxies at z~1. The data rate from DEIMOS will be in excess of 1 Gbyte/hour, and it is therefore imperative to employ completely automated data reduction techniques to manage the analysis. We here describe aspects of our data pipeline, which will make extensive use of B-splines for the sky-subtraction stage and for the combination of multiple frames.
