Abstract:

Method of transition between the ј?, B? and C? photometric sys tems are introduced on basis of their rotation adjustment in the Cartesian coordinate sys tem and on subsequent interpolation of luminous intensity values in given nodes. This allows us to reasonably define all meridian angle values in the whole range of taken values: [-?, ?] for A and B, and [0, 2?] for C.
