Left: SEDs of AT 2014ej constructed from photometry obtained between +5.1 d and +71.6 d post discovery. On each SED we overplot its best-fit BB function (solid red line) including all the available data from u to K_s, and its best-fit BB function (dashed blue line) including only the filters in common for all the epochs, namely B to i. Right: estimates of BB luminosities (from the BB fit integrations and from the CHASE r band) (top), BB temperatures (middle), and BB radii (bottom).
