The prime number theorem for primes in arithmetic progressions at large values

Assuming the Riemann hypothesis, we prove the latest explicit version of the prime number theorem for short intervals. Using this result, and assuming the generalised Riemann hypothesis for Dirichlet L-functions is true, we then establish explicit formulae for ψ(x,χ)⁠, θ(x,χ) and an explicit version of the prime number theorem for primes in arithmetic progressions that hold for general moduli q≥3⁠. Finally, we restrict our attention to q≤10000 and use an exact computation to refine these results.
