Abstract

Accurate positions of four pulsars1 have been measured with the one mile cross type radio telescope at the Molonglo Radio Observatory. This instrument2, which operates at a frequency of 408 MHz, forms eleven beams simultaneously, each 2•7’ in right ascension by 2•8’ in declination and seRefsted by 1•4’ in the north-south direction. Simultaneously with this the east-west arm can be used alone, giving a fan beam in the meridian plane 2•0’ by 4•2°. Similarly, there are eleven simultaneous fan beams available from the north-south arm; these are elongated in the east-west direction. Results from all these systems have been combined here. CP 1919 is, however, right on the northern limit of the east-west system.
