Colour composite (left panel) and colour map (right panel) of NGC 1433. Colour composites are built by collapsing the data cube in a blue (4750–6000 Å), green (6000–7000 Å), and red (7000–9000 Å) wavelength band and combining the resulting images. Colour maps are obtained by subtracting the red image from the blue.
