Effect of changes in the light deflection and parallax on the along-scan coordinate φ. The red line, calculated from Eq. (10) with δγ = 2 × 10−5, shows the maximum shift expected under current constraints on PPN γ. The blue line, computed using Eq. (9), demonstrates how δφϖ varies with θ if the parallax increases by 11.3 μas.
