TIMES OF MINIMA OF SOME ECLIPSING BINARIES IN 2002
Karska A., Maciejewski G.
March 10, 2003
During the search for new variable stars some known binary systems have been observed (see section Variables for exeplary ligh curves).
For some of them the collected data allow to determine the times of minima. CCD frames were reduced with our software developed for the SAVS sky survey.
The minima times were computed with Kwee-van Woerden method and in some cases with the digital tracing paper method. The results are presented in the table below:
