We set out to compile a catalogue of RRab pulsating variables in theSuperWASP archive and identify candidate Blazhko effect objects within thiscatalogue. We analysed their light curves and power spectra for correlations intheir common characteristics to further our understanding of the phenomenon.Pulsation periods were found for each SWASP RRab object using PDM techniques.Low frequency periodic signals detected in the CLEAN power spectra of RRabstars were matched with modulation sidebands and combined with pairs ofsidebands to produce a list of candidate Blazhko periods. A novel technique wasused in an attempt to identify Blazhko effect stars by comparing scatter atdifferent parts of the folded light curve. Pulsation amplitudes were calculatedbased on phase folded light curves. The SuperWASP RRab catalogue consists of4963 objects of which 3397 are previously unknown. We discovered 983 distinctcandidates for Blazhko effect objects, 613 of these being previously unknown inthe literature as RR Lyrae stars, and 894 are previously unknown to be Blazhkoeffect stars. Correlations were investigated between the scatter of points onthe light curve, the periods and amplitudes of the objects' pulsations, andthose of the Blazhko effect. A statistical analysis has been performed on alarge population of Blazhko effect stars from the wide-field SuperWASP survey.No correlations were found between the Blazhko period and other parametersincluding the Blazhko amplitude, although we confirmed a lower rate ofoccurrence of the Blazhko effect in long pulsation period objects.
