Light curves, finding charts, and data (CSS, SSS, MLS) are
available online in the html version of this paper as a
zip-archive. The light curves are given in the format displayed in
Fig. 1. Top panels present data folded with the fundamental-mode
and first overtone periods. Bottom panels show the same curves
after prewhitening the other oscillation (if the frequencies
and
were excluded, it is also noted). These
light curves are given for all data series.
Along with the light curves, we present power spectra of the RR Lyrae variables, for the raw data and after subtraction of the first-overtone (or fundamental mode) oscillations, as is shown in Fig. 2. The structure of the power spectra shows that the secondary periods are real.
The period ratios, , are typical of radially pulsating
double-mode RR Lyrae stars. The Petersen diagram for double-mode
RR Lyrae variables of this article is displayed in Fig. 3.
There are several cases of wrong periods in the Catalina surveys periodic variable star catalog: for Nos. 1, 5, 19, 22, 55, and 72, the period given by them is a one-day alias of the true first overtone period; for Nos. 42 and 87, the period is a one-day alias of the true fundamental mode period.
The star designations are from the USNO-B1.0 catalog (Monet et al. 2003). The tabulated coordinates of the variables were drawn from either the GSC2.3 (Lasker et al. 2008) or 2MASS (Skrutskie et al. 2006) catalogs.
For all stars,the Catalina Sky Survey (CSS) data were used in the analysis. Additionally, we used the Mount Lemmon Survey (MLS) data for Nos. 8, 10, 13, 16, 28, and 32 and the Siding Spring Survey (SSS) data for Nos. 34, 61, 118, and 123.
Information on the studied stars is presented in Tables 1-3. Table 1 contains numbers from the USNO-B1.0 catalogs; equatorial coordinates (J2000); magnitude at maximum and minimum in the Catalina surveys photometric system; period previously known for the star, according to the Catalina surveys periodic variable star catalog.
