---------------------------------------------------------------------------

Frequency reporting methods.

These methods provide information about the frequencies returned in the visibility cubes. The information can returned as the channel numbers (numbered as in the underlying MS data) or in a frame-based frequency. This information reported need not be in the same frame of reference used to select the data. If the frame of reference is specified in the call, then that is the frame that is used to calculate the frequencies. If it is not specified, then the VisibilityIterator will be queried for virtual the reportingFrame = 0; if the user has specified a reporting frame to the virtual VI then that frame will be used = 0; otherwise the frame used to select the frequencies will be used. If the user provides no frequency selection to the VI then the selection frame will TOPO.

Both the channelNumber and frequency reporting methods come in two versions: one returns a single frequency for the specified frequency index and row while the other provides all of the frequencies for the specified row. The frequency index is the zero-based index along the frequency axis of a visibility cube.
