Sep 20 at 8:47 comment added GH from MO You should emphasize in your post that $f$ is a newform and $a_f(n)=1$. The latter condition is crucial, and this is what we call normalization (of $f$, not the coefficients).

Sep 18 at 6:33 comment added Desiderius Severus @JeremyRouse Yes I am assuming that $f$ is a cuspidal Hecke eigenform (in fact even that $f$ is a newform), and that the coefficients are normalized so that the Ramanujan-Deligne bound is $a_f(n) \ll \tau(n)$ the divisor function.

Assumptions on f
Sep 17 at 16:48 comment added Jeremy Rouse Are you assuming that $f$ is a cusp form? Are you assuming that $f$ is a normalized Hecke eigenform? How are you normalizing the coefficients?
