J/AZh/78/1135 Spectrophotometric standards near DE=+40° (Tereshchenko, 2001)

Intermediate-brightness spectrophotometric standards. Standards near +40° declination. Tereshchenko V.M. <Astron. Zh. 78, 1135 (2001)> =2001AZh....78.1135T =2001ARep...45.1002T
ADC_Keywords: Stars, normal; Spectrophotometry ; Energy distributions ; Photometry, UBV ; Photometry, Vilnius Abstract: The second stage to compile a list of regional intermediate-brightness spectrophotometric standards has been completed. It includes the spectral energy distribution for 24 stars with magnitudes 7.0-8.5 near +40° declination. The range 3100-7600Å was studied with a spectral resolution of 50Å. All the stars are referenced to a single standard the circumpolar star HD 221525. The energy distributions were used to compute color indices in the UBV, WBVR, and UPXYZVS systems,as well as in the system (BT,VT) of the TYCHO catalog. File Summary:
