  \caption{LRIS Astrometry and ESI photometry of the companion of
    PSR~J0751+1807 and stars in the field. The nomenclature of the
    stars is according to Fig.~\ref{fig:fc}. The uncertainties
    listed in parentheses are instrumental, i.e., they do not include
    the zero-point uncertainty in the astrometric tie (about~$0\farcs03$ in each coordinate) or of
    photometric calibration (0.05~mag in~$B$ and 0.03~mag in both~$R$ and~$I$).}
