  Planets orbiting binary systems are relatively unexplored compared to those
around single stars. Detections of circumbinary planets and planetary systems
offer a first detailed view into our understanding of circumbinary planet
formation and dynamical evolution. The BEBOP (Binaries Escorted by Orbiting
Planets) radial velocity survey plays a special role in this adventure as it
focuses on eclipsing single-lined binaries with an FGK dwarf primary and M
dwarf secondary allowing for the highest-radial velocity precision using the
HARPS and SOPHIE spectrographs. We obtained 4512 high-resolution spectra for
the 179 targets in the BEBOP survey which we used to derive the stellar
atmospheric parameters using both equivalent widths and spectral synthesis. We
furthermore derive stellar masses, radii, and ages for all targets. With this
work, we present the first homogeneous catalogue of precise stellar parameters
for these eclipsing single-lined binaries.
