c6mekl

A multi-temperature mekal model using sixth-order Chebyshev polynomial for the differential emission measure. The DEM is not constrained to be positive. The abundance is relative to the Solar abundances set by the abund command. The switch parameter determines whether the mekal code will be run to calculate the model spectrum for each temperature or whether the model spectrum will be interpolated from a pre-calculated table. The former is slower but more accurate.

K   	 = 	  , where D is the luminosity distance

        	 to the source (cm),    is the electron density (cm  ),

      		 and    is the hydrogen density (cm  )
