        FOCUS lengthFocus

        Specify a focus measurement.

        Real      :: lengthFocus       ! length [mm] of focus scan

        The sequence of focus subscans is determined by
        lengthFocus /nSubscans /otfFocus:

         lengthFocus     ! total length [mm] of the focus scan
         /nSubscans      ! number of focus subscans
         << TD:/otfFocus       ! not yet implemented>>

         focus subscan 1 is at offset  0.0
         focus subscan 2 is at offset  lengthFocus/2
         in case /nSubscans 3:
         focus subscan 3 is at offset -lengthFocus/2
         in case /nSubscans >3:
         focus subscan 3 is at offset  lengthFocus/2
         focus subscan 4 is at offset -lengthFocus/2
         focus subscan 5 is at offset -lengthFocus/2
         focus subscan 6 is at offset  0.0
         (etc.)
