Ian is, as always, absolutely right. The only comment/correction I have
is that Hailang was apparently referring to severely incomplete model,
for which the poor phases will dominate the mFo map. Under such
circumstances, even 2fo-fc map will not correctly reflect the actual
relative contribution of the missing and already modeled regions into
electron density.
