BL Lac Monitoring

As part of our research on BL Lac objects and Flat-spectrum Quasars we carry out multifrequency monitoring. Radio-, IR-, UV-, X-ray-, and Gamma-ray observations are carried out simultaneously with optical monitoring. Finding charts and comparison sequences for some of the sources are available.
