BVRIJHK Photometry of Cepheid Variables
Contemporaneous BVRI and JHK photometry are presented for twenty-twoCepheid variables. Nineteen of these variables also have uvby photometryavailable, making them excellent candidates for application of theInfrared Flux Method of distance determination. We are in the process ofacquiring high precision radial velocities of sixteen of these variablesin anticipation of conducting that analysi. (SECTION: Stars)

Observational studies of Cepheids. II - BVRI photometry of 112 Cepheids
Over 4000 differentially determined photoelectric BVRI observations andthe resulting light curves are presented for 112 Cepheids accessiblefrom Northern Hemisphere observatories. The internal precision of thesedata is better than + or - 0.01 mag, and the accuracy of transformationto the Johnson BVRI system is nearly as good.
