We present QUIJOTE intensity and polarization maps in four frequency bands centred around 11, 13, 17 and 19 GHz, and covering approximately 30 000 deg2, including most of the Northern sky region. These maps result from 9 000 hours of observations taken between May 2013 and June 2018 with the first QUIJOTE instrument (MFI), and have angular resolutions of around one degree, and sensitivities in polarization within the range 35–40 μK per 1-degree beam, being a factor 2–4 worse in intensity. For more details, see Rubiño-Martin et al. (2023), "QUIJOTE scientific results – IV. A northern sky survey in intensity and polarization at 10–20GHz with the Multi-Frequency Instrument", MNRAS accepted .
