Elysion is definitely not a Quarter-class. It looks to be one of the original Macross-classes produced near the beginning of the New UN's expansion, rather than a New Macross-class like what was seen in 7 and Frontier.

Where did you hear it was a Quarter?

Per recent revelations in Great Mechanica G 2016 Summer, it's been confirmed that the Macross Elysion is not a Macross Quarter-class vessel.

She seems to be a similar design, but she's roughly twice the size (828m in Storm Attacker mode).

The emigrant ship on Ragna seems to be one of the very earliest New Macross-class ships. It doesn't have a shell, so it's probably Macross-1 or Macross-2.
