Summary
The median values of angular sizes of weak extragalactic radio sources, the flux densities of which lie in the range of about 0.3 to 5 Jy at 327 MHz, have been determined for a new sample of 119 sources observed during 1973–74, and agree well with the value of about 10 arc sec determined earlier by Swarup (1975). For 8 different flux density ranges, the angular size distribution for the All-sky, 3CR and Ooty radio sources have been compared with theoretical predictions based on the evolutionary model by Kapahi (1975) and show a remarkable agreement with his model except that the best fit is found for a linear size evolution proportional to (1 + z)−1.
