Polarisation signal from a corona with τ = 1 and kTe = 100 keV observed at 75° inclination with seed photons initially polarised according to Chandrasekhar calculations. The black line correspond to the extended slab corona covering the whole disc up to 1000 rg. Coloured lines show the signal as we shrink the outer radius of the corona until we reach a compact spherical corona with radius 10 rg (green line). Orange line represents a special case in which we reduced the ISCO to the value corresponding to a Kerr BH (see text for further detail).
