Abstract

A method is proposed to optimize the definition of existing photometric filters in order to minimize passband-matching problems. It is argued that the “improved” systems should generally yield better astrophysical parameters than the original ones. Although of a general scope, the method is checked on intermediate-passband filters of the Strömgren system.
