Let's see how may typos I made in this :-)

Well, what I left out is that while the density of 6^3P1
atoms in a high pressure mercury lamp is determined mostly
by the local temperature, the work of Karabourniotis shows
that the density of this state is not fully in equilibrium
with the local temperature. Therefore absorption of 254 nm
photons can increase the density of the state. However,
this departure from LTE is so slight that most of the
absorption of Hg visible lines you see in your measurements
is controlled by the temperature profile of the discharge
and not 254 nm photon absorption.
