We analysed their light curves and power spectra for correlations in their common characteristics to further our understanding of the phenomenon. Pulsation periods were found for each SWASP RRab object using phase dispersion minimisation techniques. Low frequency periodic signals detected in the CLEAN power spectra of RRab stars were matched with modulation sidebands and combined with pairs of sidebands to produce a list of candidate Blazhko periods. A novel technique was used in an attempt to identify Blazhko effect stars by comparing scatter at different parts of the folded light curve. Pulsation amplitudes were calculated based on phase folded light curves. The SuperWASP RRab catalogue consists of 4963 objects of which 3397 are previously unknown. We discovered 983 distinct candidates for Blazhko effect objects, 613 of these being previously unknown in the literature as RR Lyrae stars, and 894 are previously unknown to be Blazhko effect stars. Correlations were investigated between the scatter of points on the light curve, the periods and amplitudes of the objects' pulsations, and those of the Blazhko effect. Description: The SuperWASP RR Lyrae catalogue contains 4963 RRab type RR Lyrae objects from the SuperWASP archive. Each entry includes the unique SWASP identifier, pulsation period in days, pulsation amplitude in mags, median light curve amplitude in mags, the corresponding GCVS name, and corresponding SSS/CRTS names, where known. The SWASP blazhko candidate catalogue contains 1324 rows of Blazhko periods for 983 unique objects from the SWASP RRab catalogue. File Summary:
