We have used the IRAM PdBI-WIDEX, with its 3.6GHz of instantaneous dual-polarization bandwidth, to target 12CO(3--2) from galaxies lying in the proto-cluster at z=2.300 in the field HS1700+64. If indeed this line in DRG55 is 12CO(3--2), it's detection at 104.9GHz indicates a z_CO=2.296. None of the other eight known z~2.30 proto-cluster galaxies lying within the primary beam (PB) are detected in 12CO, although the limits are ~2x worse towards the edge of the PB where several lie.
