J/AZh/71/468  Spectrophotometric Standards near the Pole  (Tereshchenko, 1994)

Regional Spectrophotometric Standards of Intermediate Brightness: Standards around the Northern Celestial Pole Tereshchenko V.M. <Astron. Zh. 71, 468 (1994)> =1994AZh....71..468T
ADC_Keywords: Energy distributions ; Spectrophotometry Description: Absolute energy distributions for 13 circumpolar (δ>+85deg) stars forming a spectrophotometric version of the North Polar Spectrophotometric Sequence (NPSS) are presented. A-type stars of 5-9mag brightness were studied in the range 3100 to 7750A with resolution of 50A. Observations were made with 0.5-m and 1-m telescopes using Seya-Namioka spectrometers. The relative rms error of results in the region 4000-7000A is 2 to 3%, while at the ends of the studied range it is 3-5%. The primary standard was the circumpolar star HD 221525 (V=5.58, A7IV), and its spectral energy distribution had been determined earlier. File Summary:
