The authors provide absolute fluxes for four very metal‑deficient F‑type subdwarfs (HD 19445, HD 84937, BD +26 2606, BD +17 4703) based on the adopted spectral energy distribution of the primary standard α Lyrae, with additional data for HD 140283. Fluxes are measured in 40‑Å bands spanning 3080–12 000 Å for four ≈ mag 9 stars distributed across the sky, intended as secondary standards for absolute spectrophotometry. Published in The Astrophysical Journal (1983) with DOI 10.1086/160817.

B. ; Gunn, J. E. Abstract Based on an adopted absolute spectral energy distribution for the primary standard star Alpha Lyrae, absolute fluxes are given for the four very metal-deficient F type subdwarfs HD 19445, HD 84937, BD + 26.2606 deg, and BD + 17.4703 deg. Somewhat inferior data are also given for HD 140283. The data are given for 40-A bands and cover the wavelength range from 3080 A to 12,000 A. The four stars, all near magnitude 9 and distributed around the sky, are intended as secondary standards for absolute spectrophotometry.
