Fit of a limb emission spectrum, tangent altitude 37.0 km. Three species are fitted
simultaneously, and a fit of T is included. The fit nicely reproduces the actual
T at the tangent point.

Please note: The Levenberg-Marquardt break has been switched on to ensure proper
convergence. The fixed built-in convergence criterion seems to be too stringent in
case of an emission spectrum, so I reduced the max number of iterations. (Perhaps I
will give the user some flexibility to adjust the convergence criterion in the next
release of the software.)

Spectrum measured by MIPAS-B limb sounder on 020924 (flight 11, Air-Sur-l'Adour).
