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