Looks like there is a numerical problem with integration, these plots of pdf do not look very nice. Happened after I vectorized the Koen functions. The plots should have the same shape Generated these plots with:
mmin = .03 mmax = 120 gamma = .9 sigma = .4 m = np.logspace(-3,3) def integrand(x,y): return (x**-(gamma+1)) * np.exp(-.5*((y-x)/sigma)**2) coef = gamma/((sigma*np.sqrt(2*np.pi)) * ((mmin**-gamma) - (mmax**-gamma))) def Int(y): I = quad(integrand, mmin,mmax,args=(y))[0] return I vector_I = np.vectorize(Int) pbb = coef* vector_I(m) masses = np.logspace(-3,3) noerror = imf.KoenTruePowerLaw(.03,120,.9) pdf_noerror = noerror(masses) smallerror = imf.KoenConvolvedPowerLaw(.03,120,.9,.05) pdf_smallerror = smallerror(masses) pl.loglog(masses,pdf_smallerror) pl.loglog(masses,pdf_noerror) pl.loglog(masses,pbb)
