Generate a realization of the present energy spectrum on the required grid. It robotically computes and stores grids for the shears and convergence. The quantities which are returned are the theoretical shears and convergences, usually denoted gamma and kappa, respectively. ToObserved to convert from theoretical to observed portions. Note that the shears generated utilizing this technique correspond to the PowerSpectrum multiplied by a sharp bandpass filter, set by the dimensions of the grid. 2) (noting that the grid spacing dk in ok space is equivalent to kmin). It’s price remembering that this bandpass filter is not going to look like a circular annulus in 2D okay house, electric power shears shears but is relatively more like a thick-sided image frame, having a small sq. central cutout of dimensions kmin by kmin. These properties are visible within the shears generated by this technique. 1 that specify some issue smaller or bigger (for kmin and kmax respectively) you want the code to make use of for the underlying grid in fourier area.

However the intermediate grid in Fourier space will be larger by the required components. For Wood Ranger Tools correct representation of energy spectra, one mustn’t change these values from their defaults of 1. Changing them from one means the E- and B-mode power spectra that are enter will be valid for [Wood Ranger Tools](http://www.ardenneweb.eu/archive?body_value=%3Cp%3E%3Cimg+loading%3D%22lazy%22+src%3D%22https://powerefficiency.com/wp-content/uploads/2025/03/Wood-Ranger-Power-Shears-Review-4-1024x576.webp%22+alt%3D%22Wood+Ranger+Power+Shears+Review+-+Power+Efficiency%22+style%3D%22clear:both
