Gaia focal plane. The viewing directions of both telescopes are superimposed onto this common focal plane which features 7 CCD rows, 17 CCD strips, and 106 large-format CCDs, each with 4500 TDI lines, 1966 pixel columns, and pixels of size 10 μm along-scan by 30 μm across-scan (59 mas × 177 mas). Source images cross the focal plane from left to right. For the photometric calibration explained here, only CCDs in the Astrometric Field and Blue and Red Photometers are relevant.
