- Author contribution statement
- The fundamental measurements in the Gaia astrometric instrument (Section 2), are the locations and fluxes of the stars. This process, known as image parameter determination (IPD), requires calibrations including the PSF, background and CCD response. In addition to developing the IPD, Davidson implemented the calibrations in the cyclic processing system. The stellar locations and fluxes are respectively the primary inputs to the astrometric solution and G-band photometry (Sections 3.1 & 3.2). Many low-level issues are present in this data release; Davidson contributed to the analysis of the systematic residuals presented in Sections 6.3.1 and 6.3.2.
