Notes. Description of the fields: (1) SDSS target name in terms of truncated J2000 RA and Dec in the format HH.MM.SS.ss+DD.MM.SS.s. (2) Right Ascension (RA) in degrees. (3) Declination (Dec) in degrees. (4) Plate-MJD-Fiber of the spectrum for the BOSS target. (5) QSO redshift from the BOSS pipeline. (6) Background LAE redshift inferred from the peak detection. (7) Signal-to-noise ratio of the detected line. (8) Wavelength ratio aλ (Rhoads et al. 2003), further described in Sect. 3.2. (9) g-band magnitude. (10) i-band magnitude. (11) Mass (1012 M⊙) enclosed within the maximum detectable Einstein radius θE = 3.6″, assuming a singular isothermal sphere (SIS) model and flat ΛCDM cosmology (Planck Collaboration XIII 2016), giving an approximate upper bound on the lens mass. (12) Apparent flux (continuum subtracted) of the Lyman-α emission in units of 10−17 erg cm−2 s−1.
