Hi Christopher & Steve, thanks for your replies.
The version I need is the generalisation of open & proper morphisms
(i.e. some kind of map f_*\Omega_F -> \Omega_E) rather than the
generalisation of locally connected & tidy morphisms (some kind of
functor F -> E). As Steve says, I think the results I want follow from
the stability of the hyperconnected-localic factorisation, but I was
hoping someone had written out the details in the style of sections
C3.1 & C3.2 of the Elephant. Looks like I'll have to do it myself.
Barney.
