Correcting second-order contamination in low-resolution spectra
arXiv:0705.3441 · doi:10.1002/asna.200710779
Abstract
An empirical method for correcting low-resolution astronomical spectra for second-order contamination is presented. The method was developed for correcting spectra obtained with grism #4 of the ALFOSC spectrograph at the Nordic Optical Telescope and the performance is demonstrated on spectra of two nearby bright Type Ia supernovae.
