#17 Estimate spectral resolution

[skamann]

Hi Christer,

it would be very helpful if p3d could give an estimate of the spectral resolution in an exposure.
I think in principle it shouldn't be a big deal to calculate this: If p3d fits the arc-lines with Gaussians when running the "Fit centroids"-function, it would be sufficient to divide the wavelength of the line by the best-fit FWHM of the Gaussian and to store/print the mean value for every line.

Many thanks,
Sebastian
