GravityfieldCovariancesPropagation2GriddedData
This program computes the covariance between a source point given by longitude/latitude (L, B) and the points of a grid in terms of the functional given by kernel from the variance-covariance matrix of a gravityfield evaluated at time.
If computeCorrelation is set, the program returns the correlation according to \[ r_{ij} = \frac{\sigma_{ij}}{\sigma_i \sigma_j} \]in the range of [-1, 1] instead of the covariance.
