Integrated spectrum of the SagDIG H II region. The left panel shows the window wavelength of the Hγ and [O III]λ4363 emission lines. The middle panel shows the Hβ and [O III]λλ4959,5007 emission lines. The right panel shows the spatial distribution of the selected fibres to generate the integrated spectrum of the SagDIG H II region with auroral detection. The colour code represents the jump value of each selected fibre. The grey contours represent the Hβ emission of the nebula as reference.
