BYSpec: An Automatic Data Reduction Package for BFOSC and YFOSC Spectroscopic Data
Abstract BFOSC and YFOSC are the most frequently used instruments in the Xinglong 2.16 m telescope and Lijiang 2.4 m telescope, respectively. We developed a software package named “BYSpec” (BFOSC and YFOSC Spectra Reduction Package) dedicated to automatically reducing the long-slit and echelle spectra obtained by these two instruments. The package supports bias and flat-fielding correction, order location, background subtraction, automatic wavelength calibration, and absolute flux calibration. The optimal extraction method maximizes the signal-to-noise ratio and removes most of the cosmic rays imprinted in the spectra. A comparison with the 1D spectra reduced with IRAF verifies the reliability of the results. This open-source software is publicly available to the community.
