Background map (scatter map) used in the pipeline for the four CCD rows in strip 16 (strip 16 in the Gaia focal plane is numbered 2 in the RVS focal plane). On the y-axis is the across scan (AC) direction plotted as CCD row number, while the x-axis is the Gaia solar phase angle. This scatter map is obtained using the VOs acquired during the 28 days of operations, when Gaia was in EPSL mode (first trending epoch). The scatter map is dominated by the solar straylight. The units are e ⁻ pix ⁻¹ (not dividedby the 4.4 s exposure time).
