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
/s in the line) while
zfeklor has an additional parameter for the redshift.
