Description
3U 1207 + 39, the X-ray source identified with the Seyfert galaxy NGC 4151, was observed on 1975 June 24 with a balloon-borne telescope. The photon number spectrum was relatively flat (power-law slope α = -1.6 +- 0.9) and consistent with previous observations. Thermal bremsstrahlung models provide poorer fits to the data. (author)
