Abstract

Spectrophotometric observations of 16 early-type stars are reported; a Reticon photodioide array was used to obtain flux distributions at 40-A resolution from 4650 to 10,000 A. Extinction corrections were determined nightly from multiple observations of appropriate stars. The observations were reduced to Hayes' and Latham's (1975) flux scale for Alpha Lyrae by means of nightly observation of that star. The observations are shown to be sufficiently accurate for use as secondary spectrophotometric standards.
