zbremss

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 for low temperatures.

par1	 =   plasma temperature in keV

par2	 =   redshift

K	 =    , where D is the distance to the

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