摘要
After having cross-identified a subsample of the Lyon-Meudon Extragalactic Database (LEDA) galaxies in the COSMOS data base, we defined the best relations to convert COSMOS parameters (coordinates, position angle, diameter, axis ratio and apparent magnitude) into the RC3 system used in the LEDA data base. Tiny secondary effects can be tested, e.g. the distance-to-plate-centre effect and the airmass effect. The converted COSMOS parameters are used to add missing parameters to LEDA galaxies.
