Description
It is hoped that 21 cm experiments will measure
the neutral fraction at redshifts z=6-10 in the
near future. We look at what current constraints
from the CMB and the Lyman alpha forest tell us
about reionization. The existing data is used to
constrain different parametrizations for the
sources that drive reionization via a likelihood
analysis. In this talk, I will discuss how this
allows us to quantify our uncertainty in the
ionization history. The resulting histories are
then used to make predictions for what 21 cm
experiments will observe and how their
observations will feed back on our understanding
of reionization.
