Description:

Preliminary results of observations of 11 globular clusters made with the aid of a narrow long slit are presented. The photometric profiles were recorded directly in the operational store of a computer with the telescope stopped om iits motion about the polar axis. The photometric profile obtained were compared with King´s models and with the generalized sychrone model. The finite length and width of the slit were considered. The theoretical brightness distribution agrees well with observation in the central regions of the clusters at R < 3´- 5´. The radii of cores Rc and the effective radii Re were determined. Large-scale fluctuations of density, possible caused by bright stars, or by fluctuations of the abundant galactic background, were observed in clusters M12, M13 and NGC 6712.
