Observational studies of cepheids. I. BVRI photometry of bright cepheids.
Abstract
Over 1,000 differentially determined photoelectric BVRI observations and the resulting light curves are presented for 24 bright Cepheids accessible from Northern Hemisphere observatories. The internal precision of these data is shown to be better than + or - 0.01 mag, and the accuracy of transformation to the Johnson BVRI system is nearly as good.
