`theta`	a `numeric` vector of size 4 (μ, σ^2, τ^2, φ) containing the parameters associated with the model.
`.dt`	a `numeric` vector containing the variable Y.
`dists`	a `list` of size distance matrices at the point level.
`npix`	a `integer vector` containing the number of pixels within each polygon. (Ordered by the id variables for the polygons).
`model`	a `character` indicating which covariance function to use. Possible values are `c("matern", "pexp", "gaussian", "spherical", "cs", "gw", "tapmat")`.
`nu`	ν parameter. Not necessary if `model` is `"gaussian"` or `"spherical"`
`tr`	θ_r taper range.
`kappa`	κ \in \{0, …, 3 \} parameter for the GW cov function.
`mu2`	the smoothness parameter μ for the GW function.
`apply_exp`	a `logical` indicater wheter the exponential transformation should be applied to variance parameters. This facilitates the optimization process.
