Spatial sky coverage of all successfully imaged ALMA archival data available for COSMOS (top panel) and GOODS-S (bottom panel) as of June 6, 2022. The blue shaded shapes are outlines of single pointings and blind surveys; the darker shades of blue indicate an overlap of multiple images. For single pointings, the circle size corresponds to the area where the primary beam attenuation is > 0.5. The outlines of blind surveys have been traced manually. For easier visibility the outlines of surveys are only drawn once, even if multiple coverages of the same survey exist in our database. The dashed coloured lines indicate the approximate outlines of different ancillary survey fields. In COSMOS: CANDELS (yellow; Grogin et al. 2011), COSMOS HST/ACS imaging (orange; Koekemoer et al. 2007), and S2COSMOS (red; Simpson et al. 2019). In GOODS-S: Hubble Ultra Deep Field (yellow; Beckwith et al. 2006), CANDELS (orange; as in Guo et al. 2013), and Hubble Legacy Fields (red; Illingworth et al. 2016).
