Diagram illustrating examples of on- and off-source NRT beam positions that were used to estimate the east-west diameters, and peak- and total H I profiles of the observed sources (see Sect. 3.2). The eastwest HPBW is 4', but we note that in reality the NRT beam is relatively more elongated in the north-south direction (≥22′) than is shown here.
