Description


PSLS simulates solar-like oscillators representative for PLATO observations. The simulator includes planetary transits, stochastically-excited oscillations, granulation and activity background components, as well as instrumental systematic errors and random noises representative for PLATO. The program also manages the existence of a time shift between groups of cameras. Planetary transits are included following Mandel & Agol (2002) equations (see http://adsabs.harvard.edu/abs/2002ApJ...580L.171M) and using the Python implementation by Ian Crossfield (http://www.astro.ucla.edu/~ianc/) at UCLA.

For more details see http://psls.lesia.obspm.fr and also Samadi et al (2019, A&A, in-press).

The package provides the code and two files storing the parameters describing the PLATO systematic errors:
- PLATO_systematics_BOL.npy: End Of Life (EOL) systematic errors
- PLATO_systematics_EOL.npy: Begining Of Life (BOL)  systematic errors

The package also provides two working examples:
- a main sequence star (0012069449.yaml) with its associated theoretical frequencies (0012069449.gsm) generated by ADIPLS pulsation code
- a red giant star (0009882316.yaml), which does not require as input theoretical frequencies.

A couple of grids of models can be downloaded from the PSLS website (http://psls.lesia.obspm.fr).

Changes history:

- 0.85 (23/03/19): minor changes to be make the code fully compatible with python3

- 0.8 (23/02/19): systematic errors are now modelled and simulated in the time domain. The jumps induced by the quasi-regular mask updates are now included.
- 0.7 (10/12/18): inclusion of PLATO systematic errors and random noise as a function of the star V magnitude
- 0.6: minor problems fixed (missing file,  link problem)
- 0.5: can perform simulation for a given input set of theoretical frequencies (i.e. from a given .gsm file) ; new parameters included in the configuration file .yaml ; various minor improvements
- 0.4: minor changes
- 0.3: first working version
