A power plant includes a gas turbine engine contained at least partially within an enclosure; an eductor system in communication with the gas turbine engine; and a blower system in communication with the enclosure and the eductor system. The unit comprises a channel estimator for determining a channel estimate from the input signals, a matrix calculator for determining an error covariance matrix of the input signals, and an estimator for determining weight factors on the basis of the channel estimate and the error covariance matrix and weighting and combining the input signals. Spheres centered about each volume center point are created, and the discrete locations in the color cube falling within each sphere are associated with the CLUT entry corresponding to that volume center point. The first panel is defined in the wall of the box portion by at least one line of weakness in the initial position and is foldable about the first hinge line from the initial position to a second position in which it is hinged outwardly from the remainder of the container.
