Table 2: Magnitudes of the objects in the field of NGC 7603 derived using "Sextractor'' (except those marked with *, which were derived separately with "phot'' taking care of the filament/halo subtraction and are affected by an error of at least 0.2 mag). Last column points out whether they are extended "E'' (as far as we can see from the available images and spectra; some further faint objects which look point-like might be extended too).
