Power per logarithmic interval of k, as defined in Eq. (45), at redshifts z = 0.35, 1, and 3 (from top to bottom). We show the “direct” model (red solid line), studied in Valageas & Nishimichi (2011), and the geometrical modification “tang.” (green dot-dashed line), given by the upper tangent that runs through the point of abscissa k. The small dashed vertical line shows the location  of the contact point of this tangent line with the “direct” curve.
