We use Bayesian analysis in order to constrain the equation of state fornuclear matter from astrophysical data related to the recent measurements fromthe NICER mission, LIGO/Virgo collaboration, and probability distributions ofmass and radius from other 12 sources, including thermonuclear busters, andquiescent low-mass X-ray binaries. For this purpose, we base our study on arelativistic hadronic mean field model including an $\omega-\rho$ interaction.Our results indicate optimal ranges for some bulk parameters at the saturationdensity, namely, effective mass, incompressibility, and symmetry energy slope($L_0$). For instance, we find $L_0 = 50.79^{+15.16}_{-9.24}$ MeV (Case 1) and$L_0 = 75.06^{+8.43}_{-4.43}$ MeV (Case 2) in a $68\%$ confidence interval forthe 2 cases analyzed (different input ranges for $L_0$ related to the PREX-IIdata). The respective parametrizations are in agreement with important nuclearmatter constraints, as well as observational neutron star data, such as thedimensionless tidal deformability of the GW170817 event. From the mass-radiuscurves obtained from these best parametrizations, we also find the ranges of$11.97 \mbox{ km}\leqslant R_{1.4}\leqslant 12.73 \mbox{ km}$ (Case 1) and$12.34 \mbox{ km}\leqslant R_{1.4}\leqslant 13.06 \mbox{ km}$ (Case 2) for theradius of the $1.4M_\odot$ neutron star.
