XXXVII - The energy distributions of 23 galactic globular clusters Welch, G. A. ; Code, A. D. Abstract Medium- to broad-band photometry of the integrated light of 23 globular clusters in the wavelength range from 1550 to 4250 Å is presented. There is good agreement with ground-based photometry and recent observations by ANS. The single X-ray cluster in our sample, NGC 1851, does not appear unusual. The photometry can be understood in terms of the kinds of stars already known to exist in globular clusters. In general, there appears to be sufficient short-wavelength radiation in these clusters to ionize any interstellar gas which may be present.
