I want to know the answer to the following question:
Who stated that Hipparchus created the first systematic star map?
All the background I'm provided with is that "Pliny reports that Hipparchus produced the first systematic star catalog after he observed a new star (it is uncertain whether this was a nova or a comet) and wished to preserve astronomical record of the stars, so that other new stars could be discovered.". Is that enough to answer the question?
Answer: yes
