Abstract: We rederive the luminosity function for the sample of DA white dwarfs fromthe Kiso Schmidt ultraviolet excess survey KUV stars using the spectroscopicmethod where the atmospheric parameters Teff and log g and absolute visualmagnitudes for each star are obtained from detailed model atmosphere fits tooptical spectroscopic data. We compare the result of our determination withthat obtained by Darling 1994 based on empirical photometric calibrations.Our luminosity function is also compared with that derived spectroscopicallyfrom the PG survey. Misclassified objects are also briefly discussed.
