Energy distributions in the spectra of 10 B to A stars
The energy distributions in the spectra of 10 stars of spectral classesB to A having V magnitude of about 8 m are obtained. The photometricaccuracy in tying in the absolute energy distributions in the stellarspectra to Vega averages no worse than 3-4%, which permits therecommendation of these stars as secondary spectrophotometric standards.
