COR-ID: Ionospheric Delays_Baltics_Multimission

The ionospheric correction files are generated from PTA-OBS and IGS-TEC. Ionospheric delays are stored as 1-way path delay in units of meters. In order to apply them to the range observations, they need to be scaled by 2/c, with c denoting speed of light in vacuum. Multiple targets may be summarized in one file. Data blocks for different targets are placed side by side organized by dates. If a target is unavailable or detected an outlier (low SCR), the entries are set to 9.
