Notes. Receiver bands 4, 8, 9, and 10 (marked with a dagger ( † )) are not yet commissioned for solar observations and were assumed to be symmetrically distributed around the “standard continuum” central frequencies (see, e.g., Table 6.1 in the ALMA technical handbook Remijan et al. 2020), similar to those of the commissioned bands.
