Automated variable star classification using the Northern Sky Variability Survey. Hoffman D.I., Harrison T.E., McNamara B.J. <Astron. J., 138, 466-477 (2009)> =2009AJ....138..466H

We have classified each of these objects into one of the five variable star classes: (1) Algol/alpha Lyr systems including semidetached, and detached eclipsing binaries, (2) W Ursae Majoris overcontact and ellipsoidal variables, (3) long-period variables such as Cepheid and Mira-type objects, (4) RR Lyr pulsating variables, and (5) short-period variables including delta Scuti stars. All the candidates have outside of eclipse magnitudes of ∼10-13. File Summary:

Note (1): Notes as follows: Yes = In Fourier region where β Lyr are expected No = Not in Fourier region where β Lyr are expected 1 = RR Lyr candidate identified by Kinemuchi et al. 2006 (Cat. J/AJ/132/1202) 2 = Possible W UMa candidate misidentified as an RR Lyr variable because it has a period in overlap region (see text) 5 = Possible false period, as discussed in the text 6 = Candidate exibits irregular photometric variations 7 = Candidate exibits semi-regular photometric variations 8 = Candidate does not contain sufficient data for classification, but is variable
