We first used a morphological pattern recognition searching routine to select possible candidates, and then visually inspected the images of these candidates to identify true merging/interacting sources. We discover 15147 new pairs of merging galaxies within 422deg2 of Red Sequence Cluster Survey 2. Furthermore, we also find nine new candidates of galaxy clusters by searching for regions with significant density enhancements of merging galaxies. This catalog has the largest number of morphologically identified interacting and merging galaxies based on consistent searching criteria. These sources provide a uniform sample of merging galaxies for further photometric and spectroscopic studies of galaxy evolution. Description: In this supplement, we present a catalog and images of morphologically identified merging galaxies in Red Sequence Cluster Survey 2 (RCS2) (Yee et al., 2007ASPC..379..103Y). RCS2 is a large sky survey using the Canada-France-Hawaii Telescope (CFHT) to look for galaxy clusters out to z∼1. File Summary:
