obs_description      = Full-CMZ H40alpha radio-recombination-line mosaic from the ALMA Central Molecular Zone Exploration Survey (ACES). The cube combines ALMA 12-m, 7-m and Total Power data and is primary-beam corrected. It is extracted from SPW33 around the H40alpha rest frequency of 99.02295 GHz, with a native spectral resolution of about 1.48 km/s.
