Spectral index map of the DEM L299 region created out of the 20 cm and 36 cm images. The position of the SNR and of the superbubble are marked in black and red (white in other figures). DEM L299 can be easily distinguished from the H ii region LHA 120-N 164, which lies to the south-west of it, because of their different spectral indices.
