Notes: the night parameters of each observation are averaged. Note that the DIMM
seeing is the standard ESO $V$-band value. The Near Infrared seeing is usually
of higher quality than at least 0.1~arcsec. 
In the column ``Included~?'' we stated whether we considered this observation run 
or did not use it, e.g., because of known technical problems or
bad weather during the observations. Furthermore, it is noted by ``Y-mod'' if
individual files were excluded from the observational run, e.g., due to
exceptional bad seeing.
For completeness, we note that five neutron star fields were already observed in December 2000 using
 ESO's NTT equipped with the {\it SOFI} instrument in the  $H$-band (66.D-0135). However, compared to the
later VLT {\it ISAAC} observations, the {\it SOFI} images were generally
less deep and suffered from worse seeing conditions. 
We do not list the NTT {\it SOFI} observations from 2000
here.
