^a $H_{\rm lim}$ indicates the faintest H-magnitude with a detection SNR of three measured close to the position of the neutron star; The $1 \sigma$ error is a result of the StarFinder photometric error, the zeropoint error, and an estimated/assumed error from comparison with 2MASS; ^b ZP states the magnitude of the zeropoints, which were obtained in the frame of ESO's calibration plan; $^{\rm ep2}$ indicates that two epochs have been used; ^c SE-2MASS-limits lists the Source Extractor limits if using relative 2MASS photometry; ^d The mass-limit is according to Sect. 5.1, $\cdots$ notes that the found objects are interesting for a second epoch observation, - states the opposite; ^e Geminga has been detected in a deeper HST ${\it F160W}$ observation with roughly 24.1 mag (Shibanov et al. 2006).
