VizieR Online Data Catalog: MRC 2011-298 radio images (Bruno+, 2024)

Images of MRC 2011-298 (Fig. 2 in the paper). A3670 was observed with the uGMRT wide-band receiver (GMRT Wideband Backend, GWB) in band 2 (120-220MHz), band 3 (250-450MHz), and band 4 (550-850MHz) for 8, 8, and 9 hours, respectively. Data were recorded in channels of width 0.34, 1.1, and 1.6MHz each for band 2, band 3, and band 4, respectively. Furthermore, the outdated narrow-band receiver (GMRT Software Backend, GSB) was active during the observations. Each observation includes pointings (~10min) on 3C380 and 3C48, which were used as flux density scale calibrators.

Bruno et al. (2019A&A...631A.173B) first presented JVLA observations of MRC 2011-298. We reprocessed these data with more sophisticated calibration and imaging strategies to obtain higher quality im ages. MRC 2011-298 was observed at 1-2GHz (L-band, CnB array configuration), 4-8GHz (C-band, both CnB and DnC array configurations), and 8-10GHz (X-band, CnB array configuration) for ~30min on-source each. In all the observations, 3C48 and J2003-3251 were used as flux density scale and phase calibrators, respectively. The data in CnB and DnC configuration were recorded in 16 and 34 spectral windows, respectively, each split into 64 channels.

The VLA Sky Survey (VLASS; Lacy et al., 2020PASP..132c5001L) is observing the sky above a declination of -40° at 2-4GHz (S-band) in B configuration. A number of snapshots of ~10s have been mosaicked to reach a typical noise level of 120uJy/beam at the nominal resolution of 2.5".
