Extractions regions on images (blue = NRC-F210M, green = NRC-F335M, red = MIR-F770W) of NGC 7023 (left) and the Horsehead (right). The exciting star is off the top of the image in both cases. The color used to designate the regions here will be used in spectral plots for those regions, the remainder of the text. The white dashed rectangles define the minimum (NIRSpec) and maximum (MIRI channel 4) IFU mosaic coverage.
