The PLATO Solar-like Light-curve Simulator (PSLS) is Python tool that aims at simulating solar-like oscillators representative of PLATO targets. It includes planetary transits, stochastically-excited oscillations, granulation and activity component (either a “stochastic “component or a spot component), as well as instrumental systematic errors and random noises representative for PLATO.
For more details see PSLS in a nutshell.

New version 1.7 (06/09/23): (1) New option “–psd” permits to save the PSD associated with the averaged light-curve (averaged over all cameras). (2) For the granulation component we have now the choice between Kallinger et al (2014)’s model (type=1, the model used so far) or a single Lorentzian component (type=0). (3) The option -M is now working properly. (4) new CESAM2K grid format stored in HDF5 files, the old type of grids can be used provided that ModelType = ‘grid-old’. (5) non-linear limb darkening can be used when 4 coefficients are defined for the parameter LimbDarkeningCoefficients (instead of 2 for a quadratic limb darkening). For more details see Change history
New version 1.6 (29/01/24): I nclusion of a spot model based on Dorren (1987)’s model. Mode properties (frequencies, heights and linewidths) can now be specified with an input TEXT file. For more details see Change history
New version 1.5 (01/07/22): IMPORTANT bug correction: since version 1.0 a wrong value for the (square) visibility of the l=1 modes was used (0.2 instead of the correct value of 1.5), this bug led to a large underestimation of the amplitude of the l=1 modes.
