Comments:


1. M-m = 0.1 P. J-H = 0.344 (2MASS). The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

2. M-m = 0.45 P. J-H = 0.195 (2MASS). The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

3. M-m = 0.45: P. J-H = 0.647 (2MASS).

Remarks:
I present the discovery of 3 new pulsating variables. 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 from the 2MASS catalogs.
