Notes. Positional values and uncertainties are given in arcseconds and are shifted into the CASTLES reference frame. The median modeled position of image A is set as the origin of the coordinate system. There is no measured position of image D from Gaia as it is below the detection limit of the Gaia satellite. The fluxes in the Magellan i-band are reported in the AB magnitude system and converted to Vega magnitudes (noted as Vega, i) using Table 1 in Blanton & Roweis (2007). The CASTLES fluxes are those of the HST F814W band and reported in the Vega system (noted as Vega, F814W). The transmission curves of Magellan and the F814W filter from HST WFPC2 have different shapes, which needs to be taken into account when comparing the GLEE with the CASTLES magnitudes.
