Data from the catalogues of Cappelluti et al. (2007) and Schinnerer et al. (2007). X-ray fluxes are given in units of 10-15 erg s-1 cm-2 and radio fluxes in units of $\mu$Jy. HR1 and HR2 correspond to the hardness ratios defined in Eqs. (4) and (5). The X-ray luminosity is in erg s-1, assuming the objects are located at redshifts z = 2.25 and 0.06 for LAE and GALEX-detected candidates respectively. Offsets are distance from centroid of narrow-band detection to X-ray/radio detection in units of arcseconds. It is expected that the objects with offsets larger than a few arcseconds (25, 57, 113, 121, 132 and 173) are unrelated to the candidates due to the large offset and the relatively large probability of random association.
