Observed Faraday depths, φ_observed, and ionFR-modeled ionospheric Faraday depths, φ_ion, toward B0834+06 as a function of time during midday (observations: blue circles, left axis labels; model: red triangles, right axis labels). Upper panels: eleven LOFAR HBA observations using the international station near Onsala, Sweden. Middle panels: eleven LOFAR Superterp HBA observations. Lower panels: eleven LOFAR HBA observations using the international station near Nançay, France. Panel a) shows the ionFR model using CODE TEC data and IGRF11; panel b) shows the ionFR model using ROB TEC data and IGRF11.
