Partial Coherence Simulation
In order to simulate the temporal and spectral distribution of SASE pulses there is an easy way based random fluctuations filtered spectrally and temporally.
The only input parameters are the center wavelength, spectral bandwidth and the pulse duration.
Below you can find a python implementation (by MartinB) of the partial coherence method as described in:

CentralEnergy=80 # in eV
bandwidth=0.5 # bandwidth in %
dt_FWHM=10, 30., 70 # FWHM of the temporal duration on average
