Summary of the ALMA detections.

ID RA(J2000) Dec(J2000) HAB z − H
(1) (2) (3) (4) (5)
a0 22.43 2.3
a1 23.25 2.2
a2 23.54 3.1
a3 23.20 (21.7) 2.3 (3.2)

Notes. (1) Source ID. (2) Source right ascension (RA) and (3) declination (Dec). (4) HST H-band (typical 1σ uncertainty: 0.02) and (5) z − H color index (typical 1σ uncertainty: 0.25). The 1σ uncertainty on the detection position is set to 0.5 × ⟨FWHM⟩ × S/N−1 (Papadopoulos et al. 2008), where ⟨FWHM⟩ is the mean of the major and minor FWHM of the beam and the S/N is that of the peak pixel. We note that a3 appears to be a blend of two galaxies at the higher spatial resolution of the HST images (Fig. 1, right); we report the magnitude and color index of the source corresponding to the bulk of CO emission (that to the east) and in parentheses the values of the other source (that to the west).
