Properties of the Molecular Arms in the Galaxies M51, M101 and IC342
Published online by Cambridge University Press: 03 August 2017
Extract
M51, M101 and IC342 were all observed in the CO(1-0) line with the Onsala 20 m antenna. “The average pointing error for a 20 minute run is less than 5”, usually considerably less, and the receivers are stable. The error lobe is considerable with an efficiency of about 40%. With a width of about 20′ it is of little importance compared to an emission region of 2′ to 3′ however. Of more concern is an upper and a lower sidelobe with a combined efficiency of about 14%.
