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 1.8 (28/01/25): 1) the duration of each quarter has now to be specified (in days); 2) the option –hdf5 saves in a HDF5 file the light-curves (LC) and the various simulation components ; 3) the oscillations, granulation and (stochastic) activity components are now simulated independently ;  4) seed numbers can be controlled independently for the stochastic activity, granulation, and oscillations components ; 5) gaps are introduced ;  6) introduce modulations in the spot radii ; 7)  groups of simulated cameras can be specified individually  ; 8) the option –proto-sas saves the data in format compatible with the prototype SAS pipeline ; 9) when sampling >25s, the systematic errors were not correctly averaged.

New version 1.7 (06/09/24):  (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
