Herschel-color image of NGC 6334: 70 μm (green, 5.9″ resolution) and column density (red, 36.6″ resolution). Blue circles are young H ii regions (seen as compact radio sources; Persi & Tapia 2010) while crosses are I and I(N), the two highest column density peaks of NGC 6334. The yellow polygon represents the mapped area of SIMBA-1200 μm observations, the white box represents the extent of SCUBA2 450/850 μm observations, the blue box highlights the highest-density parts of NGC 6334 presented in Sect. 3.1 and Fig. 2, and dashed orange lines outline the Galactic latitude range we associated with NGC 6334 (0.3°< latitude < 1.1°) to build the HOBYS catalog.
