  (noise variance) 23 0.008
  1. These are the parameters of the Gamma distributions from which we sample the RBF- hyperparameters. For example, the characteristic lengthscale is sampled from a Gamma with scale 1.4 and shape 5.7. The hyperparameters are then used in the RBF covariance function to sample/simulate a profile from the Gaussian process.
