feklor, zfeklor: Fe K fluourescence line at high resolution

A seven Lorentzian approximation to the line profile of Fe K fluourescence from neutral material. The energies, widths, and relative amplitudes for the Lorentzians are taken from Holzer et al (1997) and are:

Energy (eV) Width (eV) Amplitude  
6404.148 1.613000 0.387653  
6403.295 1.965000 0.209121  
6400.653 4.833000 0.048943  
6402.077 2.803000 0.075640  
6391.190 2.487000 0.188543  
6389.106 2.339000 0.033370  
6390.275 4.433000 0.056730  

The only parameter for feklor is the normalization (the total photons/cm$^2$/s in the line) while zfeklor has an additional parameter for the redshift.
