Top: Fermi/LAT smoothed count map between 200 MeV and 100 GeV in Galactic coordinates. The bright source at the centre of the field is FGL J1045.0-5942. The source located  ~1.3° to the North is the pulsar PSR J1048-5832. Bottom: Fermi/LAT significance map corresponding to a zoomed image of the black box shown in the upper image. The blue cross indicates the optical location of η Carinae. The green circle is the 95% confidence region reported for 1FGL J1045.2-5942 (based on 11 months of data). The plain black circle shows the 95% confidence region found in our analysis of the 21 month dataset. The dashed circles show the 200 MeV to 8 GeV and 10 GeV to 100 GeV confidence regions. The cyan circle corresponds to the confidence region of the hard X-ray detection obtained with INTEGRAL (Leyder et al. 2010).
