This paper is a refutation of two researches by A. N. Sazonov on HZ Her andV1341 Cyg published in the Astronomy Reports (Vol. 55, p.p.142 and 230) in2011. We analyzed his photometry along with other data collected in theliterature and Internet. The observations of Sazonov are fake and are notrelated to real stars. Conclusions contained in his papers do not constituteany scientific value. We describe the properties of these two objects, derivedfrom real observations. The following papers based on the same fakeobservations 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.
