Scientific paper

The energy distributions of 11 horizontal-branch A stars in the four globular clusters M5, M13, M15, and M92, and nine field stars in the 1 HLF 2 field are measured using the multichannel spectrometer on the 5-m telescope on Palomar Mountain. Measurements are made at 16 wavelengths between 3410 and 6840 A. The observations are reported here as absolute energy distributions on the system of Hayes and Latham (1975). The (internal) measurement error (std. dev.) is 0.034 mag per observation, averaged over all wavelengths.
