Gaussian process kernel parameters: posterior distribution of GP kernel parameters for the April 9, 2019, data set. The total variance K₀ was fixed to equal the noise-bias corrected variance of the light curve, and only the scale parameters c and d were estimated. The dashed lines are placed at the 16, 50, and 84^th quantiles of the marginalised one-dimensional distributions. The fractional error in the estimation of parameter c is about 10%.
