Gaussian Process: light-curve fits

PISCOLA uses tinygp to fit the multi-colour light curves. These are fit in 2D, i.e. flux (plus errors) as a function of time and wavelength at the same time. This allows PISCOLA to do a more informative interpolation and extrapolation.

The available kernels are: Matern32 (Mátern-3/2), Matern52 (Mátern-5/2) and ExpSquared (Squared-Exponential).

For information about the available functions, check the Gaussian Process functions.
