Abstract
The goal of astronomical spectroscopy is to produce a wavelength calibrated line profile of the spectrum of an astronomical object, usually a star. From this line profile of the spectrum image, wavelengths can be measured as well as equivalent widths. Stellar and supernova classifications can be done. Doppler shifts can be measured and radical velocities calculated. Elemental lines can also be identified and their strengths measured. All these data can be gleaned from a single image of a spectrum. No wonder spectroscopy is so powerful.
