However a table would need to hold a number of samples (e.g. annual, daily, minute) that have the same date/time., vector timeseries is timestamped series of tuple of magnetic field components characterising the field vector over the cadence period, Geomagnetic observation Derived from Processing history, not well-defined concept comment quasi-absolute, Geomagnetic Index Made at Geographic location, poorly defined state comment reported
