Scientific paper

This paper presents the complete uvby light curves of the eclipsing binary TZ For, obtained on 148 nights during the time period 1976-1984. The TZ For binary consists of two evolved well-separated late-type stars F7 III + G8 III in a circular orbit. The obtained uvby light curves of TZ For are suitable for the analysis with modern light curve synthesis methods. However, due to the small geometrical depth of the eclipses, it is impossible to determine the important parameter k = r(B)/r(A) (and, therefore, the individual radii) from the photometric measurements alone.
