org.orekit.models.earth.displacement.OceanLoadingCoefficientsBLQFactory

public class OceanLoadingCoefficientsBLQFactory
extends AbstractSelfFeedingLoader

Factory for ocean loading coefficients, using Onsala Space Observatory files in BLQ format.

Files in BLQ format can be generated using the form at the Bos-Scherneck web site, selecting BLQ as the output format.

The sites names are extracted from the file content, not the file name, because the file can contain more than one station. As we expect existing files may have been stripped from headers and footers, we do not attempt to parse them. We only parse the series of 7 lines blocks starting with the lines with the station names and their coordinates and the 6 data lines that follows. Several such blocks may appear in the file. Copy-pasting the entire mail received from OSO after completing the web site form works, as intermediate lines between the 7 lines blocks are simply ignored.
