Map of the region around the studied cloud constructed by overlapping the maps in H I (HI4PI Collaboration 2016, −13 km s⁻¹) and H II (Finkbeiner 2003). The default map intensities were re-scaled with the use of a power law (see the colour bars) for a better contrast between the images. The stars used to analyse the spectra of Ca II are displayed as yellow circles; β Sco and δ Sco are marked with a plus and a cross symbol, respectively. Contours of the dust map from Edenhofer et al. (2024) at a distance of 107 pc are also presented (from black to white: A_V = 9, 16, 23, and 30 mmag pc⁻¹).
