##### Initial condition for Psi typo
« on: 19. April 2021, 15:07:40 »
There was a small typo on the website where the initial condition for $$\Psi$$ was $$+2/3$$ when it should be $$-2/3$$ to match the plots on the website (which has $$\Phi$$ positive). This sign has no effect on the final results (power-spectra) we are going to compute as they are squares of the perturbations, but all the plots will just be mirrored along the y-axis if you use the other sign. If you have already made plots and used + instead of - then that is perfectly fine.
