  <dt>uband</dt>
<dd><p>numeric, zoo, data.frame or matrix object with the streamflows representing the the upper uncertainty bound of <code>x</code>, for which the flow duration curve have to be computed. <br>
Measurements at several gauging stations can be stored in a data.frame of matrix object. When <code>uband</code> is a matrix or data.frame, the flow duration curve is computed for each column.</p></dd>
