Because of the primitive file naming limitation in ISO9660, some file names on this CD are incomprehensible. BET > BETA CA > UVBYCA COU > COUSINS DDO > DDO GEN > GENEVA JHK > JHKCIT RIJ > RIJKL T13 > THIRTEEN UBV > UBV VBL > VBLUW VBY > UVBY VIL > VILNIUS These systems are generally normalized to Vega except that VBLUW is normalized to alpha Leo. The spectrophotometry for 109Vir and for HD19445, which have been used as standards, can not be fit by this grid. DDO IS NOT NORMALIZED AND CANNOT BE USED AS IS. THE USER MUST SET THE ZERO POINT. These computed colors should be used with caution. It is probable that the transformation from the natural computed system to the standard system is nonconstant or nonlinear and can only be found by comparing to many standard stars. The models may be physically incorrect.
