Note (1): Dominant period and its full amplitude.  All blank fields are non-periodic variables. 
          In cases where the periodicity analysis is affected by a large scatter of light curves 
          due to photometric bias or source blending, 
          we used the already known period in that source from the previous catalog (Harman et al. 2008b).
Note (2): u and z magnitudes from the Sloan Digital Sky Survey (SDSS) DR7 (Abajazjian et al. 2009)
Note (3): g, r, and i magnitudes from Hartman et al. (2008a) and SDSS DR7 catalog.
Note (4): B and V photometry from Kalirai et al. (2001).
Note (5): J, H, and Ks photometry from the Two Micron All Sky Survey (2MASS) Point Source Catalog (Cutri et al. 2003).
Note (6): Type of variability. The following types of variability were assigned: 
          F = flare stars, 
          P = pulsating variables, 
          mp = multi-periodic variables, 
          R = rotating variables, 
          EB = eclipsing binary systems, 
          A = aperiodic variables, and : (or var:) = variable candidates.  
	  We also use the two cases: Non = non-variables listed in Table 1, 
                                     U = These variable objects fell on chip gaps and were not observed.
