Examples of sources. From left to right the columns display (1) the HST image in the F775W or F850LP filter (2) the emission or absorption narrowband for the main line (3) the spectrum zoomed-in on the main line (in blue) and its fit (in red) (4) the full spectrum (in blue). The green curves show the noise standard deviation. Except for the first two sources, the narrowband images and the full spectra have been filtered with respectively a Gaussian of 0.5″ FWHM and a box filter of 5 pixels. Image sizes are 5″ × 5″. Observed wavelengths are in Å and the flux unit is 10⁻²⁰ erg s⁻¹ cm⁻² Å⁻¹. For each source the MUSE identifier, depth in hours, redshift value and confidence, and AB HST magnitude are indicated.
