Example of a source with a dubious spectro-z of 1.39. The ALHAMBRA photometry and errors, represented by the black dots and crosses, provide a photo-z solution (continuous line) of 2.53 with peak emission-lines from L_α, C III] , and C IV clearly visible at ~4300, ~5400 and ~6700 Å  respectively. Lines and symbols as in Fig. 4. The spectra of this source is currently unavailable to the public.
