cyclabs: absorption line, cyclotron

A cyclotron absorption line as used in pulsar spectra. See Mihara et al. (1990), or Makishima et al. (1990).

$$M(E)=exp\left[-D_f\frac{(W_fE/E_{cycl})^2}{(E-E_{cycl})^2+W_f^2} + D_{2h}\frac{(W_{2h}E/2E_{cycl})^2}{(E-2E_{cycl})^2+W_{2h}^2} \right]$$

par1=$D_f$	depth of the fundamental
par2=$E_{cycl}$	cyclotron energy
par3=$W_f$	width of the fundamental
par4=$D_{2h}$	depth 2nd harmonic
par5=$W_{2h}$	width of the 2nd harmonic
