RT Journal Article T1 Hß photometry for uvby standard stars A1 Reglero, V. A1 Giménez, A. A1 Fabregat, J. A1 Castro Rubio, Elisa De A1 Fernández Figueroa, María José A1 Castro, A. de AB From 1984 to 1986, we made several observational campaigns at Calar Alto and La Palma Observator­ies using the uvby and ß photometric systems to monitor a selected sample of late-type variable stars. In this paper we present the ß values for 38 uvby standard stars to contribute to the uvby-ß calibration works on late-type stars. In the final discussion, the ß computed values are plotted against the Ström­gren b - y, m_1, and c_1 indices.

The JKT on the island of La Palma and the l.5 m Tele­scope at Calar Alto are operated, respectively, by the Royal Greenwich Observatory at the Spanish Roque de los Mucha­chos Observatory (Instituto de Astrofísica de Canarias), and Observatorio Astronómico Nacional at the Spanish Ca­lar Alto Observatory (Almería). We want to express our gratitude to the staffs of the observatories for their help dur­ing the observational campaigns.
