Sažetak
We present complete archives of calibrated differential UBV photometry of many bright stars, secured in the course of our systematic observing program of bright northern Be stars carried out at the Hvar Observatory between 1972 and 1990. Altogether, 76 Be stars of all luminosity classes were observed and 13848 differential UBV measurements were secured. A limited number of observations of some other variables (mostly CP stars) is also included. The archives also contain differential observations of many check stars and some red stars, observed during the program as transformation standards. Some of these red stars may in fact be low-amplitude variables. Altogether, the archives contain 33581 observations of 481 different stars. A careful transformation of all observations into the standard Johnson system was carried out. Besides the final data archives, we also present here all seasonal data sets with original observations which could be re-reduced with a better software in the future if desirable.
