Sven Zschocke, Sergei A. Klioner
TL;DR
This paper simplifies the light deflection formula for solar system objects by neglecting higher-order terms, enhancing the efficiency of Gaia data reduction.
Contribution
It introduces a simplified transformation in post-post-Newtonian order, reducing computational complexity for astrophysical measurements.
Findings
Neglected all post-post-Newtonian terms of order m^2/d^2.
Total sum of these neglected terms is less than 15/4 pi m^2/d^2.
The simplified formula improves Gaia data processing efficiency.
Abstract
The transformation n to k in post-post-Newtonian order is simplified. All post-post-Newtonian terms of the order m^2/d^2 are neglected and we show that the total sum of these terms is smaller than 15/4 pi m^2/d^2. This simpler transformation will improve the efficiency of Gaia data reduction.
