Significance map as obtained in the CT5 mono analysis, for the combined DS-I (0.78 < p < 0.96) and DS-II (1.09 < p < 1.10) using an oversampling radius of 0.1°. The positionof η Car is denoted with a black star and the long-dashed ellipse refers to the uncertainty in the positional fit as described in the main text. The positions of the nearby Fermi-LAT sources 4FGL J1048.5−5923 and 4FGL J1046.7−6010 are shown with blue crosses (The Fermi-LAT Collaboration 2019). The inlay shows the point spread function (PSF) as obtained using run-wise simulations (RWS) in colour, while the overlaid dotted circle indicates the PSF using classical simulations.
