Test statistic (TS) maps of the celestial region around 2FGL J1045.0−5941 as obtained by likelihood analysis. The TS-value corresponds to the likelihood of the source being located in a specific grid point. Left plot: 0.2 to 10 GeV, right plot: 10 to 300 GeV. The confidence contours (green for the high band, white for the low band) mark the 68.3%, 95.4% and 99.7% uncertainty regions for the location of the source of interest. The dashed yellow circle marks the catalogued 95% source location region of 2FGL J1045.0−5941. The nominal position of η Car is indicated by the yellow cross.
