Fig. 3
False-color representation of the HST Hα image of η Car and the Keyhole Nebula with superposed contours of the LABOCA map. The numbers 1–5, A1, B, and C refer to the CO clumps in the Keyhole Nebula defined in Cox & Bronfman (1995). The contour levels in this image start at 0.06 Jy/beam and increase on a logarithmic scale by factors of 1.364 (i.e. 0.135 dex).
