Fitting string inflation to real cosmological data: the Fibre Inflation
  case
  In this paper we show how the string landscape can be constrained using
observational data. We illustrate this idea by focusing on Fibre Inflation
which is a promising class of string inflationary models in type IIB flux
compactifications. We determine the values of the microscopic flux-dependent
parameters which yield the best fit to the most recent cosmological datasets.
