Parameters of the Gamma distributions for sampling the RBFhyperparameters. 

Sampling Gamma distribution Γ(a, b) 



a (scale) 
b (shape) 



Sampled RBF Hyperparameters 
ℓ^{2 }(characteristic lengthscale) 
1.4 
5.7 


(signal variance) 
2.76 
0.2 



(noise variance) 
23 
0.008 



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.
