SED fitting results for ILTJ160658.74+550607.0, obtained using  BAGPIPES. Left: reduced χ² for SED fits in the range 0 < z < 8, with locations of the Lyα, [OII], and [OIII]+Hβ emission lines indicated by dashed black lines. The dashed grey lines indicate the redshift range probed by the NB filter for the strong emission lines [OIII], [OII], as well as Lyα. Right: observed flux of ILTJ160658.74+550607.0 (blue) in mJy with the original errors and posterior median model (yellow) for fits with redshifts fixed at z = 0.84, 1.47, and 6.57. The source is best fitted by a template with z = 1.47 when considering the possible emission lines. No other emission line is strong enough for the source to be at z ~ 4.
