Note that a finer granularity description of the sensitivity of band 6a has been implemented between LO = 1440 and 1448 GHz. This will usually result in lower noise and shorter observation time for noise-driven AORs in this band.

Sideband ratios -- an imbalance between upper and lower sidebands exists at a number of frequencies. This shows up in the messages available for each time estimation as a difference in sensitivity (system temperature) between the upper and lower sidebands at the given LO frequency setting. This imbalance is most obvious for the lowest frequencies in band 2a.
