| 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 SOFI instrument in the H-band (66.D-0135). However, compared to the later VLT ISAAC observations, the SOFI images were generally less deep and suffered from worse seeing conditions. We do not list the NTT SOFI observations from 2000 here. |
