- Multi-line-fits with blends: The contribution from each line is visible in the plot
- Error analysis of amplitudes: The correlated errors are calculated, i.e.
in line blends the errors are larger than the formal errors (cf. A.W. Strong,
Astron. & Astrophys.
**150**, 273, 1985). - The fit can be forced to satisfy linear restricting conditions in the form (Sect. 7.1): with weight factors for each line.
- New input parameter
*spec_only*and*fit_only*for suppressing plot of fitted curve (without fitting) and plot of the spectrum, respectively - More Options:
- Gauss/Lorentz profile function
- Iteration of and FWHM (in versions prior 3.2 ) can be turned off individually
- Lock switch locking the wavelength of a line to the value of the
previous line

Multiplet fitting is preserved - Pseudo-Voigt (weighted sum of Gauss and Lorentz, with a common linewidth also calculated from individual Gauss and Lorentz line-widths cf. Sect. 7.3).
- The log-file [e.g. cora.dat] can be converted into a L
^{A}TEX table

- Parameter files are backward compatible!
