  We observe EIT in a V-system in a thermal rubidium-87 vapour in the hyperfine
Paschen-Back regime, realised with a 0.6 T axial magnetic field. In this regime
energy levels are no longer degenerate and EIT features from different initial
states are distinct, which we show produces a much cleaner feature than without
a magnetic field. We compare our results to a model using the time-dependent
Lindblad master equation, and having averaged over a distribution of
interaction times, see good qualitative agreement for a range of pump Rabi
frequencies. Excited state decay into both ground states is shown to play a
prominent role in the generation of the transparency feature, which arises
mainly due to transfer of population into the ground state not coupled by the
probe beam. We use the model to investigate the importance of coherence in this
feature, showing that its contribution is more significant at smaller pump Rabi
frequencies.
