Abstract

X-ray spectral data from a rocket-borne proportional counter exposure to discrete sources in Cygnus are presented. The data from Cyg x-1, Cyg X-2, and Cyg X-S have sufficient statistical significance to clearly indicate mutually exclusive spectral forms for the three. Upper limits are presented for X-ray intensities above 2 keV for Cyg X-4 and Cyg X-5 (Cygnus Loop).
