Total ALMACAL survey area vs the median sensitivity range reached in each band for the pruned sample. For comparison, we plot the area and sensitivity values from the previous surveys, PHIBSS2 (Lenkić et al. 2020), COLDz (Riechers et al. 2019), ASPECS (Decarli et al. 2016) in ALMA Bands 3 and 6, GOODS-ALMA (Gómez-Guijarro et al. 2022) in ALMA Band 6, and AS2UDS (Stach et al. 2019) in ALMA Band 7. The dashed light and dark lines show the total area accumulated by summing up all the bands for the pruned sample and the full sample. The total survey area counts every calibration field once, considering the largest area.
