SIC UVT_VERSION

        [SIC\]SIC UVT_VERSION Version

    [EXPERIMENTAL -- Reserved for developpers so far]

    Select the UV Table version being used by SIC.  The Version can be  FRE-
    QUENCY,  DOPPLER or SYSTEM.  It affects the way the spectral axis is in-
    terpreted to define spectral and spatial resolution.

    FREQUENCY is the "old" historical behaviour, which is only suitable  for
    small field of views and number of channels.

    DOPPPLER is suitable for large number of channels, but may be limited to
    small field of views in case of data spanning several observation dates

    SYSTEM is more accurate, but requires an extra column in the  UV  Tables
    to hold time dependent Doppler tracking.
