dc.description.abstract	We have investigated the area of two NGC entries, NGC 1817 and NGC 1807, with deep CCD photometry in the uvby–Hβ intermediate-band system. The photometric analysis of a selected sample of stars of the open cluster NGC 1817 yields a reddening value of E(b − y) = 0.19 ± 0.05, a distance modulus of V0 − MV = 10.9 ± 0.6, a metallicity of [Fe/H] = −0.34 ± 0.26 and an age of log t = 9.05 ± 0.05. Our measurements allow us to confirm that NGC 1807 is not a physical cluster.	es_ES
