Fig. 8
Observed Faraday depths, φobserved, and ionFR-modeled ionospheric Faraday depths, φion, toward three pulsars as a function of time during sunrise (observations: blue circles, left axis labels; model: red triangles, right axis labels). Upper panels: twelve LOFAR Superterp HBA observations of PSR B1642−03. Middle panels: twelve LOFAR Superterp LBA observations of PSR B1919+21. Lower panels: twelve LOFAR Superterp HBA observations of PSR B2217+47. The vertical dashed lines indicate the time of sunrise. a) Shows the ionFR model using CODE TEC data and IGRF11; b) shows the ionFR model using ROB TEC data and IGRF11.
