Automating Reduction of Multifiber Spectra from the MMT Hectospec and Hectochelle
Abstract
Hectospec, the MMT's low resolution, 300 fiber spectrograph, posed some interesting and unique problems for reduction software development. To address these issues as well as the usual ones encountered in a multifiber spectrograph, we built a semi-automatic reduction pipeline, SPECROAD, using host IRAF CL scripting. The pipeline is based on existing IRAF tasks, modified when necessary, with some locally-developed procedures added. For quality control purposes, some human interaction was kept in the process. The pipeline takes raw data and produces one-dimensional, wavelength calibrated, sky subtracted, and velocity correlated spectra that are automatically distributed to their owners and added to a database. We are currently developing a pipeline for the 240-fiber Hectochelle high-dispersion spectrograph and we will discuss the additional issues which have complicated its data reduction.
