5. M–m = 0.14 P.

6. M–m = 0.1: P.

7. M–m = 0.16 P.

8. M–m = 0.5 P. EW type with a twice longer period is also possible.

9. M–m = 0.30 P.

10. M–m = 0.19 P.

11. M–m = 0.34 P.

12. M–m = 0.18: P.

13. M–m = 0.40 P.

14. M–m = 0.27 P.

15. M–m = 0.5: P. The period considerably varies.

16. M–m = 0.27 P.

17. M–m = 0.37 P.

18. M–m = 0.13 P.

19. M–m = 0.16: P.

20. M–m = 0.43 P.

21. M–m = 0.35 P.

22. M–m = 0.4 P.

23. M–m = 0.30 P.

24. M–m = 0.45 P. Combined brightness of two stars (probably the SE component of 3'' pair is variable: J = 13.66, J–K = 0.27; the NW component: J = 14.31, J–K = 0.71).

25. M–m = 0.35 P.

26. M–m = 0.45 P.

27. M–m = 0.25 P.

28. M–m = 0.35 P.

29. M–m = 0.47 P.

31. M–m = 0.2: P.

32. The elements are for JD 2453606–2454386. The period possibly varies.

33. M–m = 0.12 P.

34. M–m = 0.15: P.

36. M–m = 0.14 P.

37. M–m = 0.1: P.

38. M–m = 0.13: P.

Remarks:
We present light elements and types for 38 pulsating stars found in the process of improving coordinates of variables from the NSV catalog (Samus et al. 2007–2015). HV 9863, HV 9956, HV 10001, and HV 10053 were found, upon our request, by the late Dr. Martha L. Hazen in Harvard Observatory's logbooks. No finding charts were available for these variables before. We study the variables using publicly available electronic archives of CCD observations of the ASAS-3 project (Pojmanski 2002) and the Catalina Sky Survey photometric data (Drake et al. 2009).
