Table 3: Apparent magnitudes of objects in the filament between NGC 7603 and NGC 7603B. The R-Bessel magnitude was measured for three different epochs, the Sloan filters for only one epoch. Magnitudes in the Johnson filters and bj photographic filter were calculated from the magnitudes in the Sloan filters (see text). Columns 3 and 4 give the observed apparent magnitudes (uncertainty $\sim $0.2 mag.). Columns 5 and 6 give the same magnitudes corrected of Galactic extinction (Schlegel et al. 1998) and filament extinction (by means of Eqs. (3) and (4)).
