Overview of the NGC 2023 & NGC 2024 region, showing a DSS2-blue optical image of the region, with the integrated CO emission from Fig. 18 overplotted as blue and red (for the brightest regions) contours, and APEX Laboca 870 μm dust continuum as yellow contours. Yellow stars mark the position of HOPS protostars, and cyan lines mark the location of the position-velocity cuts shown in Fig. 20. The red line marks the cut along the NGC 2024 monopolar outflow axis (shown in Fig. 29), the green line marks the cut along the dark lane (shown in Fig. 25).
