Optical polarimetric observations of the black hole binary star Cyg X-1 with RoboPol

The dataset contains raw FITS images of the black hole X-ray binary star Cyg X-1, raw FITS images of a nearby field star used for the interstellar polarization correction and processed measurements of polarimetric standards used for the instrumental polarization correction. The dataset was obtained with the RoboPol optical polarimeter in the R-band mounted at the 1.3 m telescope of the Skinakas Observatory, Greece. The data were collected between 13 May and 1 June 2022.
