The PLATO Solar-like Light-curve Simulator (PSLS) is Python tool that aims at\u00a0 simulating solar-like oscillators representative of PLATO<\/a> targets. It includes planetary transits, stochastically-excited oscillations, granulation and activity component (either a \u00ab\u00a0stochastic \u00ab\u00a0component or a spot component), as well as instrumental systematic errors and random noises representative for PLATO.<\/p>\n

If you use this simulator in your research, please cite Samadi et al (2019, A&A, 624, A117)<\/a>. Thanks !<\/p>\n

New version 1.9<\/strong> (02\/09\/25):\u00a0 1) correct bug when using stellar grid (HDF5 file) ; 2)\u00a0 mode splittings are now included in more complete way ; 3) save the setup (YAML) in the HDF5 file ; 4)\u00a0 inclusion of flares, based on a prescription established by F. Baudin ; 5) the user can impose any additional stellar component, which is taken from an external TEXT file ; 6) compatibilty issue with numpy.acos() replaced by numpy.arccos()<\/p>\n

New version 1.8<\/strong> (28\/01\/25): 1) the duration of each quarter has now to be specified (in days); 2) the option \u2013hdf5 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 ;\u00a0 4) seed numbers can be controlled independently for the stochastic activity, granulation, and oscillations components ; 5) gaps are introduced ;\u00a0 6) introduce modulations in the spot radii ; 7)\u00a0 groups of simulated cameras can be specified individually\u00a0 ; 8) the option \u2013proto-sas saves the data in format compatible with the prototype SAS pipeline ; 9) when sampling >25s, the systematic errors were not correctly averaged. For more details Change history<\/a>.<\/p>\n

New version 1.7<\/strong> (06\/09\/24):\u00a0 (1) New option \u00ab\u00a0–psd\u00a0\u00bb 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).\u00a0 (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<\/a><\/p>\n

New version 1.6<\/strong> (29\/01\/24):\u00a0 I nclusion of a spot model based on Dorren (1987)’s model.\u00a0 Mode properties (frequencies, heights and linewidths) can now be specified with an input TEXT file. For more details see Change history<\/a><\/p>\n
