bremss

A thermal bremsstrahlung spectrum based on the Kellogg, Baldwin & Koch (ApJ 199, 299) polynomial fits to the Karzas & Latter (ApJSuppl 6, 167) numerical values. A routine from Kurucz (priv. comm.) is used in at low temperature end. The He abundance is assumed to be 8.5% of H by number.

par1	 = 	plasma temperature in keV

K	 =       , where D is the distance to the


	       source (cm) and   ,    are the electron and ion densities (cm  )
