8.8
* bugfix in definition of kappaSPM. The bug led to an overestimation of the SPM strength and was revealed by benchmarking the chi3D code with a very well defined spectral broadening experiment published in Kaumanns et al., Opt Lett 43, 5877 (2020).

* the timing (GD and GDD) in the spectral domain is now available in a 3D-plot (GD/GDD vs. angle and frequency)
* there is a new posibility to set signal beam radius in the unconsiderd dimension (which is necessary for the estimation of the pulse energy) to be always as big as the pump radius as it is written in the input field by typing "inf" this is important for batch-loops with chaning pump radius
