his is done by the following
        functions:

            - C{self.FIXERS['magneticVariation']}
            - C{self.FIXERS['latitudeFloat']}
            - C{self.FIXERS['longitudeFloat']}

        @param coordinateType: Coordinate type. One of L{Angles.LATITUDE},
            L{Angles.LONGITUDE} or L{Angles.VARIATION}.
        @param sentenceDataKey: The key name of the hemisphere sign being
            fixed in the sentence data. If unspecified, C{coordinateType} is
            used.
        @type sentenceDataKey: C{str} (unless L{None})
