Revisited analysis of the double lensed source 14, made of a pair of knots, at the depth of MDLF. Top panel: continuum-subtracted one-dimensional spectrum of the pair obtained from the sum of the three multiple images 14a + 14b + 14c, equivalent to ≃51 h of integration. High-ionization lines are detected at S/N ∼ 10 − 50, while the inset shows the deficient Lyα emission (the same scale on Y-axis is adopted), ∼8 times fainter than C IVλ1548, or ∼4 times fainter than C III]λ1907. Bottom-left panel A: HST color image (red = F105W, green = F814W, blue = F606W) for the least magnified image (image 14[1 + 2]f), where the upper limit on the separation between knots 1 and 2 is quoted (s <  0.06″). Panels B and C: narrow-band (NB) continuum-subtracted MUSE images of the same 14[1 + 2]f, centered at the C IVλ1548 line and at the weight average of seven lines (the CHOC complex, see text for details). The NB images have been smoothed with a Gaussian kernel (σ = 1 pix). The red circles indicate the MUSE PSF of . The same HST color image for the most magnified images 14.2b and 14.1b is shown in the bottom-right E panel, while the corresponding C IVλ1548 MUSE narrow-band image is in panel D. The small open white circle shown in the HST cutouts marks the F814W PSF.
