Integral under Î_r, ^∫Î_rdr (top), rms difference between Î_φ and , (middle), and position of the centre of the Venusian disc in terms of the cosine of the heliocentric angle, μ = cosθ (bottom) as a function of time from 22:00:00 UTC, June 5, 2012. The red circles highlight the values for the filtergrams used to derive the PSF. The dashed lines mark the approximate time of the second and third contacts; the period between which the Venusian disc was entirely within the solar disc from SDO’s position.
