After having cross-identified a subsample of LEDA galaxies in the COSMOSdatabase, we defined the best relations to convert COSMOS parameters(coordinates, position angle, diameter, axis ratio and apparent magnitude) intoRC3 system used in the LEDA database. Tiny secondary effects can be tested:distance to plate cenetrs effect and air-mass effect. The converted COSMOSparameters are used to add missing parameters on LEDA galaxies. Key words: galaxies - catalogue - photometryComment: 5 pages, postcript including figures, to appear in MNRAS, reprint requests: dinella@mpia-hd.mpg.d
