Comments: The continuous absorption of NH3 began near 1210 A and extended to the shorter wavelengths. The structure of the 
absorption contour suggested the existence of two ionization continua: a weaker one with maximum sigma = 21 Mb at 1130 ± 20 A 
and a larger one with its maximum of 34 Mb at 730 ± 20 A.
