Agreement between complementary determinations of the SNLS AB offsets. SNLS BD+17 and SNLS SA lines refer to the SNLS calibration on Landolt standards and direct solar analog measurements respectively (cf. Sect. 4). The SDSS SA and SDSS BD+17 lines refer to the calibration obtained by translating the PT measurements of the solar analogs and BD +17 4708 respectively, to the SNLS system via the relations obtained in Sect. 8. The data points correspond to the calibration offset relative to the combined calibration including all the measurements and are not independent. The shaded region illustrates the uncertainty on the combined calibration.
