  • dbaad65c5a MAJOR REV: FIXED 2LPT SIGNS, WHICH WERE ACTUALLY CORRECT!! Note to myself: don't fix signs while listening to talks!! Other mods/fixes: * 2LPT is now supported also with distinct baryon/DM power spectra. This creates now an overhead when using Eisenstein&Hu or BBKS. But who cares. * Reverted to determinant formulation of LLA rather than second order expansion. This is much more accurate. * Added baryon density filter. Baryon density field is now consistent with CIC DM density. This is achieved by convolving with an additional grid cell filter (and no deconvolution). * Tested LLA, skewness is now exact to a few per cent but tends to be systematically higher. * 2LPT needs a bit less memory now in multigrid mode (FFT based 2LPT still needs humongous amounts). * Cleaned up code output. Oliver Hahn 2010-07-31 05:38:55 -0700
