Optical Counterparts of the X-ray Sources Hercules X-1 and Cygnus X-2: Genuine and Fake

Abstract

This paper is a refutation of two researches by A. N. Sazonov on HZ Her and V1341 Cyg published in the Astronomy Reports (Vol. 55, p.p.142 and 230) in 2011. We analyzed his photometry along with other data collected in the literature and Internet. The observations of Sazonov are fake and are not related to real stars. Conclusions contained in his papers do not constitute any scientific value. We describe the properties of these two objects, derived from real observations. The following papers based on the same fake observations and published by him in astro-ph arXiv:0904.0168, arXiv:0907.3822, arXiv:0912.0706, arXiv:1011.3980, and arXiv:1102.0379 are also inauthentic.
