# What is the proper area for a Gaussian Pulse so it will be able to perform a rotation of pi on a qubit?

with pulse.build(backend, name='hadamard') as h_q0:
pulse.play(Gaussian(duration=1289, amp=0.99, sigma=32), pulse.drive_channel(0))

reg = pulse.measure(qubit)

h_q0.draw()


Above is code that I have for a Gaussian Pulse. How would you change the duration, amp, and sigma parameters, so that the Gaussian Pulse would have the proper area for conducting an X gate on a qubit?
