This data release corresponds to the paper "Constraining scalar-tensor gravitational theories by GW190426_152155" (arXiv:2105.13644). In this paper, we consider three specific models of scalar-tensor theories, including the Brans-Dicke theory (BD), the theory with scalarization phenomena proposed by Damour and Esposito-Far\`{e}se (DEF), and Screened Modified Gravity (SMG). We use the public GW data of a possible neutron star-black hole binary event, GW190426_152155, to place the constraints. Four equations of state (EoSs), sly, alf2, H4 and mpa1, are used to derive the scalar charges of neutron stars for BD and DEF. The constraints are obtained by performing the full Bayesian inference with the help of the open source software Bilby. This dataset contains all posterior samples of the runs discussed in the paper. The models and EoSs can be read form the filenames for the runs of BD and DEF. The files of "*_half_dipole.json" correspond to the runs for constraining the dipole radiation without considering specific model parameters. All files are JSON format which is the default output format of Bilby. They are human readable and also can be processed or visualized by Bilby or PESummary conveniently.
