We present binding energies of hydrogen states in magnetic fields B = 0 to B approximate to 5 x 10(8) T, relevant for the modeling of the atmospheres of magnetic white dwarfs and neutron stars. We analyzed states with magnetic quantum number m = 0, ... , -4 and included states up to a principal quantum number n = 15 for a total of 300 states. Due to a sophisticated data point selection we can interpolate any energy value for each of these states with an absolute precision of at least 10(-6) Ry for any magnetic field strength. Further, and also as a function of the magnetic field strength, we present dipole strengths of all transitions between these states relevant for the Lyman, Balmer, Paschen, and Brackett series, with similarly high precision.
