Surface Photometry of NGC 3379 with a Tektronix 2048 × 2048 CCD Camera — Comparison with the Luminosity Profile of de Vaucouleurs and Capaccioli
The development of large-format CCDs offers a new opportunity to study the luminosity distribution in galaxies. In this paper we present the first astronomical photometry with a Tektronix 2048 × 2048 CCD. The U. S. Naval Observatory large format CCD camera with an engineering setup grade, front illuminated Tektronix 2048 × 2048 CCD was used on the 40-inch Ritchey-Chretien telescope at the Flagstaff Station to measure the luminosity profile in NGC 3379. We compare the result with the E-W luminosity profile published by de Vaucouleurs and Capaccioli (1979, hereafter dV+C), and we describe some of the features of the CCD.
