Abstract

We present a method for deriving most optimal filter system by which the accuracy of derived physical quantities can be maximized. Using Kurucz(1978)'s model atmospheres, an optimal four filter system for F and G dwarfs is suggested, for which mean wavelengths are located at $3400{\AA}$, $3850{\AA}$, $4190{\AA}$, and $4600{\AA}$ with half-bandwidth of $200{\AA}$. It is found that 35, 38 and 42 filters of the DDO system and the $Str{\ddot{o}}mgren$ u and $\nu$ filters are close to those of the most optimal system.
