Notes. See text for description of the model components.

^(a)

Fixed to the Galactic column density from the Dickey & Lockman (1990) HI maps.

^(b)

Absorption and thermal component abundances fixed to those of the LMC.

^(c)

kT fixed to 0.1 keV, appropriate for the LHB emission (see text).

^(d)

Normalisation fixed to equivalent of 10.5 photons keV cm^-2 s^-1 sr^-1 (see text).

^(e)

Numbers in parentheses are the 90% confidence intervals.
