=====================================

.. py:function:: earthkit.meteo.extreme.array.sot_func(qc_tail, qc, qf, eps=-0.0001, lower_bound=-10, upper_bound=10)

   Compute basic Shift of Tails (SOT) using already computed percentiles

   :param qc_tail: Tail percentile value (99% or 1%)
                   Model climatology
   :type qc_tail: :class:`array-like (npoints)`
   :param qc: Upper or lower percentile (at 90% or 10%)
              Model climatology
   :type qc: :class:`array-like (npoints)`
   :param qf: Upper or lower percentile (at 90% or 10%)
              Ensemble forecast
   :type qf: :class:`array-like(npoints)`
   :param eps: Epsilon factor for zero values
   :type eps: :class:`(float)`
   :param missing: missing points values where denominator is zero
   :type missing: :class:`(float)`

   :returns: SOT values
   :rtype: :class:`array-like (npoints)`
