Notes. Information given in this table: (1) Object identification; (2, 3) α and δ J2000; (4, 5) AUTO magnitudes and error bars in H band; (6, 7) SExtractor stellarity index and maximum FWHM measured on the detection H + Ks image; (8, 9, 10) lensing magnification (high-z and low-z hypothesis) and associated uncertainty; (11, 12, 13) quality grade for high-z candidates according to three criteria: possible contamination by close neighbours (Q1), completeness and quality of photometric SED (Q2), and UV luminosity (Q3); (14) total grade Q; (15) optical χ2, and (16) tentative classification between low and high-z using a stringent prior in magnitude. In the case of z1 and J1 (in brackets), the low-z indentification is forced based on the detections in the 24 μm and z850 bands, respectively, for z1 and J1 (see Sect. 4.6).
