UVBY photometry of HIPPARCOS stars
Photoelectric data in the uvby system have been obtained for 367southern stars of the Hipparcos Input Catalogue. Most of the stars are Fand G main sequence and fall in the magnitude range V = 9 to 10.
| Visual measurements of southern double stars. II
A group of 248 micrometric observations of 104 double stars arepresented, forming the second series of a program carried out at Cordobawith a 30 cm refractor. Usually neglected IDS pair south of -60 deg areselected for observation, most of them having been measured only one ortwo times previously. The measurements are compared with all the earlierobservations to derive estimates for the personal equation in P.A. andseparation, and the nature of many pairs is discussed by making use ofcatalog proper motions.
