Ideally, the beam maps would be made for a single, strong standard calibrator; however, because we are limited in this run to the same block of time as NGC 2903 and also because of its declination, there is not a single suitable source. Note that sources which transit close to the zenith cannot be observed in drift mode if the ZA gets too low, For these continuum observations, we use a 50 MHz bandwidth centered at 1405 MHz. ...
