Characteristics of the sky model components assumed in our analysis.

Comp. G. Lon. position [deg] G. Lat. position [deg] Lon. extent (FWHM) [deg] Lat. extent (FWHM) [deg]

NB −1.25 −0.25 5.75 5.75
BB 0.00 0.00 20.55 20.55
Disk 0.00 0.00 141.29 24.73
GCSab −0.06 −0.05 0.00 0.00
Craba −175.44 −5.78 0.00 0.00
Cyg X-1a 71.34 3.07 0.00 0.00

Notes. The parameters are similar to those of Skinner et al. (2014), except for the extent of the disk. The disk extent has been chosen according to a 2D gridscan for a total maximum likelihood over all 80 bins (see Sect. 3.1).


An extent of 0° is equivalent to a point source.


The Galactic Centre Source has been chosen to coincide with the position of Sgr A* (see text for details).
