J1939-6342

J1939-6342 (Figure 1) has an additional ~20% flux contribution from other sources in the field at 900 MHz, and up to 40% at 600 MHz with its spectrum turning over at ~1 GHz. These sources cause time-variable ripples across the bandpass in both phase and amplitude (examples shown in Figure 2). While the standard CASA flux density models can be used for L-band data reduction, it is essential to use multi-component models for UHF observations.

A full discussion of the observations and models are included in the this commissioning report below. The SDP calibrator pipeline is currently using 90 components. This is sufficient for most cases.

J0408-6545

...

This source has somewhat lower interference from other sources in the field (1% contribution at L-band); there is a bright double-lobed source at the 1% (integrated flux) level 5.5 arcmin away from the central source.
