28-40 GHz variability and polarimetry of bright compact sources in the QUIJOTE cosmological fields

VLA program To assess the impact of bright, compact sources on the QUIJOTE data, we have monitored the brightest sources in the cosmological fields in polarization and total intensity with the VLA, between 28 and 40 GHz. The results of the monitoring programme are described in Perrott et al. (2021), "28 – 40 GHz variability and polarimetry of bright compact sources in the QUIJOTE cosmological fields", and contained in a catalogue that it is publicly available here.
