Comments:


1. MinII = 13.8:. MinII–MinI = 0.65P, D = 0.04P.

2. MinII = 13.11.

3. MinII = 13.3.

4. MinII = 13.82.

5. MinII = 14.5.

Remarks:
We checked several poorly studied variable stars from the NSV Catalogue (Samus et al. 2007–2012) and found light elements for them. We could study the variables thanks to the publicly available electronic archives of CCD observations of the ASAS-3 project (Pojmanski 2002). NSV 8162, NSV 8180, NSV 8345 were suspected by Swope (1943), NSV 9580 was suspected by Swope (1940), and NSV 8541 was suspected by Shapley and Boyd (1937).

Acknowledgments: Our studies are supported by the Program "Origin and Evolution of Stars and Galaxies" of the Presidium of Russian Academy of Science.
