Secondary UVBY standards in the Harvard E-regions Photoelectric uvby photometry for 201 stars which are already UBV (RI)cstandards is presented. The photoelectric data are closely tied to theCousins uvby standards and the stars should be suitable for use asfainter (7-11 mag) secondary standards.
Redshifts of galaxies in the Fornax cluster Among the accurate radial velocities presented for 51 galaxies in theFornax cluster, 17 redshifts have been determined for the first time. Across-comparison with prevous data indicates that the quoted mean errorsare truly external ones, with the average mean error for these radialvelocities being 27 km/sec. This accuracy demonstrates the potential forredshift determinations based on use of the ESO's Boller and Chivensspectrographs, together with the IDS.
UBV photometry of E region standard stars of intermediate brightness Photometry data are given for 335 stars in the nine E regions.Observations were made using a photometer and filters on the 47 cmreflector at Cape Town. The stellar dispersions are summarized. Data arepresented in tabular form.
