PotentialCoefficients2BlockMeanTimeSplines
This program is a simplified version of Gravityfield2TimeSplines. It reads a series of potential coefficient files (inputfilePotentialCoefficients) and creates a time splines file with spline degree 0 (temporal block means) or degree 1 (linear splines). The time intervals in which the potential coefficients are valid are defined between adjacent points in time given by splineTimeSeries. Therefore one more point in time is needed than the number of potential coefficient files for degree 0.
The coefficients can be filtered with filter. If set the expansion is limited in the range between minDegree and maxDegree inclusivly. The coefficients are related to the reference radius R and the Earth gravitational constant GM.
This program is useful e.g. to combine monthly GRACE solutions to one file.
