New Targets for Science Verification: Band 2

New Science Verification targets that will demonstrate the Band 2 receivers are now listed on the Science Verification.

The possible targets are:

• G31.41+0.31: spectral scan at 1 km/s from 67 GHz to 90 GHz to demonstrate imaging capability at ~0.4” angular resolution for line forests and capability to detect complex organic molecules.

• Arp 220: spectral scan at 10 km/s covering CO isotopologues (12CO, 13CO and C18O) and dense gas tracers (HCN, HCO+, HNC) to demonstrate imaging capability at ~0.4” angular resolution and science capability of tracing CO and dense gas tracers with the same band.

• SPT 0027-50: Spectral scan covering CO (4-3) and CO (3-2) (plus HCN, HCO+, HNC and CI (1-0)) at 10 km/s spectral resolution to demonstrate unique redshift identification at z = 3.444 via more than one CO transition.

• HR 5907: continuum full polarization observations to demonstrate the capability of detecting circular polarization and changes within the frequency range covered by Band 2 thanks to the increased fractional bandwidth.

The data are planned to be taken with about 25 antennas and will be released for public use; the release of any Science Verification data will also be preceded by a similar announcement.
