public class FreqOffset

extends AEDF

Frequency offset information.

The table contains frequency offset information to be added directly to the defined frequency labeling in the SpectralWindow sub-table as a Measure offset. This allows bands with small time-variable, ad hoc frequency offsets to be labelled as the same spectralwindowId, and calibrated together if required. This table may also be useful for fine tuning in the definition of the spectral windows for the radiometers as small frequency offsets may be present from one such device to an other. However it may be necessary to use a more general solution by defining one spectral window for each radiometer in case there is not only a global offset from one device to an other.
