Red Giant

In close connection with a parallel theoretical study (see Sweigart, Greggio and Renzini 1987) CCD photometry in the B and V bands of star clusters in the LMC and SMC was started in 1983 using the ESO telescopes. To study the development of the red giant branch (RGB) we selected intermediate age clusters using the following criteria: 1) integrated (B-V) color between 0.3 and 0.6 and/or 2) membership in the type IV group of the Searle, Wilkinson and Bagnuolo (1980) classification (SWB). A few other clusters (e.g. NGC 121) were observed for calibration purposes. The observed clusters are NGC 121, 152, 1756, 1831, 1841, 1987, 2164, 2173, 2209, 2249, 1466, 1866, 2107, 2108 and 2134 and good or very good quality CM diagrams have been obtained for the first ten of them. Out of this list, those clusters with a well developed RGB are NGC 121, 152, 1841, 1987 and 2173. Using the CCD frames, integrated (B-V) colors have also been obtained for some of the clusters.

Made In

I should like to give you a very condensed progress report on some spectrophotometric measurements of objective-prism spectra made in collaboration with H. Leicher at Bonn. The procedure used is almost completely automatic. The measurements are made with the help of a semi-automatic fully digitized registering microphotometer constructed by Hög-Hamburg. The reductions are carried out with the aid of a number of interconnected programmes written for the computer IBM 7090, beginning with the output of the photometer in the form of punched cards and ending with the printing-out of the final two-dimensional classifications.

Centre Region

In the course of several 21-cm observing programmes being carried out by the Leiden Observatory with the 25-meter telescope at Dwingeloo, a fairly complete, though inhomogeneous, survey of the regionl11= 0° to 66° at low galactic latitudes is becoming available. The essential data on this survey are presented in Table 1. Oort (1967) has given a preliminary report on the first and third investigations. The third is discussed briefly by Kerr in his introductory lecture on the galactic centre region (Paper 42). Burton (1966) has published provisional results of the fifth investigation, and I have discussed the sixth in Paper 19. All of the observations listed in the table have been completed, but we plan to extend investigation 3 to a much finer grid of positions.
