Abstract: MGHalofit is a modified gravity extension of the fitting formula for the matter power spectrum of <a href="http://ascl.net/1402.032">HALOFIT</a> and its improvement by Takahashi et al. MGHalofit is implemented in <a href="http://ascl.net/1106.013">MGCAMB</a>, which is based on <a href="http://ascl.net/1102.026">CAMB</a>. MGHalofit calculates the nonlinear matter power spectrum P(k) for the Hu-Sawicki model. Comparing MGHalofit predictions at various redshifts (z<=1) to the f(R) simulations, the accuracy on P(k) is 6% at k<1 h/Mpc and 12% at 1<k<10 h/Mpc respectively.
