An optical spectrophotometric atlas of supernova 1987A in the LMC. II - CCD observations from day 198 to 805
Additional Document Info
CCD spectrophotometry of SN 1987A in the Large Magellanic Cloud covering days 198 to 805 since outburst is presented. A total of 36 observations were obtained over this period with the Cerro Tololo 1.5 m and 4.0 m telescopes. The spectrophotometric calibration is shown to be accurate to 2%-3% over most of the observed wavelength range. Radial-velocity measurements of the peaks of several prominent emission lines and the P Cygni absorption minima of H, H, A, and Na I D are given.
