Notes.

a

The spectral resolutions and associated RMS noise are given for the best spectral resolution of our products, close to the WIDEX channel spacing. The channel spacing achived at the IRAM-30m was about 10 times smaller.

b

NOEMA had 8 antennas in 2016. With 12 antennas and the On-The-Fly observing mode, the same data quality would have been achieved with 26 hours of NOEMA observatory time.
