Notes: \\
The radial distance $d$ [\arcsec] is measured from the nominal cluster 
 center defined in Stetson's catalog of photometric standards
(\citealt{standards}; $\alpha=13^{\rm h}12^{\rm m}55\fs26$;  $\delta=+18\degr10\arcmin09\farcs 8$ [2000.0]);  errors corresponding to the last digits of the periods are shown in parentheses (see Sect.~\ref{gendesc} for details on the computation of the errors);  the signal-to-noise ratio (SNR) was calculated in the $[0.0,20.0]$~d$^{-1}$ frequency range; the $V$ and $V-I$ magnitude averages (i.e., the zero frequency constant in their 
 Fourier decompositions) are given in those cases in which the flux-to-magnitude conversion was reliable  (see Sect.~\ref{method} and Fig.~\ref{plc-test}); stars denote new detections, RRab, RRc and RRabB/RRcB stand for   fundamental, first overtone and Blazhko variables, Fourier decompositions of the RR Lyrae stars with magnitude-transformed  light curves in $V$ color are available online at CDS.
