LSDCat LAE candidates. (a.1, a.2): LAE candidate spectra obtained obtained using 1″ apertures centered at the coordinates reported in Table 1. Dashed red and purple lines show the expected wavelength of the emission at the quasar systemic and PDLA redshift. The solid black line shows a Gaussian model fitted to the data. Propagated 1σ errors are shown as vertical blue lines. (b.1, b.2): LSDCat output detection significance maps at the wavelength channel where the peak of Lyα emission is reached.
