Notes.

(a)

QSO Lyα luminosities obtained by integrating each QSO spectrum in ±FWHM of the nebular emission.

(b)

Lyα luminosities within the 2σ contours of Fig. 2 for the three QSOs. For the two SMGs, 2σ upper limits rescaled assuming a nebula area of 20 arcsec2 (from the 30 Å narrow band).

(c)

2σ upper limits on the C IV and He II luminosities. For the three QSOs, these are obtained for the Lyα nebula area within the same velocity range as the fitted Lyα line (). For BR1202-0725, most of the velocity range redward of the He II line falls outside of the spectral range of the MUSE datacube; therefore, we used the same velocity span but shifted to the last available channels. While for the SMGs, the limits are obtained assuming a nebula area of 20 arcsec2 within a velocity range equivalent to the Lyα 30 Å narrow band.

(d)

Area of the Lyα nebulae inside the 2σ contour.

(e)

SFR obtained from the Lyα luminosities listed in this table, assuming case B recombination and Formula 2 in Kennicutt (1998; see Sect. 5.1.2).

(f)

Velocity shift between the QSOs’ systemic redshift and the Lyα peak velocity of the integrated nebula spectrum computed as first moment. For completeness, the velocity shifts computed using simply the maximum of each spectrum are 332 ± 29, 444 ± 273, and 382 ± 272 km s−1 for BR1202-0725, G09-0902+0101, and G15-1444-0044, respectively.

(g)

FWHM of the Gaussian fit of the integrated Lyα emission shown in Fig. 2.

(h)

2σ SB limits for an aperture equivalent to the nebula area (assuming 20 arcsec2 for the ALESS SMGs), and in a velocity range equivalent to the 30 Å narrow band used for Lyα, in units of erg s−1 cm−2 arcsec−2.
