Spectral setup and frequency coverage of our five tunings (shown in different colors) in ALMA band 3 for the source SPT0103-45. In each tuning, four spectral windows covering 1.875 GHz each were placed in contiguous pairs in the lower and upper sidebands (LSB/USB). Note that the frequency range 96.2–102.8 GHz (delimited by dotted vertical lines) is covered twice. The total spectral range is indicated by the dashed vertical lines. The top panel shows the atmospheric transmission across band 3 at Chajnantor for 3 mm precipitable water vapor (PWV).
