Abstract

This dataset contains all the data that was used for the paper named "Densities of small planets around the M dwarfs TOI-4336~A and TOI-4342 with ESPRESSO: Three sub-Neptunes, one super-Earth, and a Neptune-mass candidate". It includes the time series of radial velocity measurements of ESPRESSO, as well as other ancillary indicators (e.g., full width at half maximum). We also provide the PyOrbit outputs of our final analysis containing the priors, posteriors and samples of posteriors, as well as the photometric and RV timeseries used.
