Observers at the National Optical Astronomy Observatories have provided spectrophotometry for 25 stars in the visual magnitude range 7.5 to 16.6. This document describes the machine-readable version of their results as received from P. Massey. The magnitudes are on the Hayes-Latham system and cover the wavelength range from 3200 to 8100 angstroms at approximately two angstrom intervals.
