A non-perturbative calculation of the gyrotropic pressures associated with large-scale
mirror modes is performed, taking into account a finite, possibly anisotropic
electron temperature. In the small-amplitude limit, this leads to an extension of
an asymptotic model previously derived for cold electrons.
A model equation for the profile of subcritical finite-amplitude large-scale structures
is also presented.
