DBSP_DRP: A Python package for automated spectroscopicdata reduction of DBSP data

Abstract

In astronomy, the spectrum of light emitted from astrophysical sources is of great use, allowing astronomers to classify objects and measure their properties. To measure the spectrum of a source, astronomers use spectrographs, in which dispersive elements spatially separate the incoming light by wavelength, and detectors, most commonly CCDs, image this dispersed light. But to do science with the spectrum, the 2D image in pixel coordinates taken by the CCD must be converted into a 1D spectrum of flux vs. wavelength. This process of converting 2D CCD images into 1D spectra is called data reduction.
