De-reddened spectral energy distribution of Qatar-1, for Av = 0.1 and d = 195 pc. Optical V and R photometric data are taken from the TASS Mark IV catalogue (Droege et al. 2006). Infrared data are taken from the 2MASS and WISE databases (Cutri et al. 2003, 2012). The NextGen synthetic low-resolution spectrum (Hauschildt et al. 1999) with the same photospheric parameters as Qatar-1 is over-plotted with a light-blue line.
