Table 8

Source height h of the corona fitted for an inner accretion disc at the ISCO using the model relconv-lp.

Parameter 1 2 3 4

h(rg) > 92 > 94 > 98 > 86
Δχ2 + 65 + 39 + 116 0

Notes. The parameter Δχ2 refers to the additional χ2 in comparison to fitting a truncated disc model for the same degrees of freedom (Table 6). In all cases the source height h pegged at the hard limit of 100 rg, therefore only lower limits were calculated.
