Uniform transformations and extinction variations for the UBV system
Abstract
The paper presents UBV measurements from a total of 55 nights for four consecutive years which show that with some precautions very uniform transformations to the standard system may be obtained. It is demonstrated that uniform transformation and extinction calculations for periods of the order of ten help to correct individually for extinction, and that such individual corrections are important.
