TREPS
TREPS (Transformations de Repères En Physique Spatiale) enables to transform vector time series (magnetic fields, velocities, positions, ...) in a choice of heliospheric reference frames. Input data may be a local file (ASCII, CDF, netCDF, VOTable), a URL or come from manual edition or via the SAMP protocol. The tool also handles different common time formats. Transformations are based on Spice Kernels from NAIF enabled in 3DView (access via web services).
