Comments:


1. MinII = 15.3. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

22. MinII = 14.45. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

23. MinII = 14.3. D = 0.10P. The RS-type variability in maximum brightness is possible.

34. Independent discovery of variability. The period in Hoffman et al. (2008), P = 0.55711, is wrong. MinII = 13.4.

35. MinII = 14.1.

36. MinII = 13.7. Type EA is not excluded, D = 0.11P. The ROTSE data w ith photometric correction flags (usually rejected) were kept for the analysis.

38. MinII = 14.6.

39. MinII = 14.4. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

40. MinII =13.2.

42. MinII = 14.7.

43. MinII = 13.3.

44. MinII = 14.2. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

Remarks:
I present the discovery of 44 new short-period eclipsing binaries (mostly EW). A search for variables was carried out in the publicly available data of the Northern Sky Variability Survey (NSVS, Wozniak et al., 2004, also see http://skydot.lanl.gov/nsvs). These observations were analyzed using the period-search software developed by Dr. V.P. Goranskij for Windows environment. The coordinates were drawn either from the Tycho-2 or 2MASS catalogs.
