Where are end portal coordinates?

Upon entering the End, a 5×5 horizontal platform of obsidian is generated centered at block coordinates (100, 48, 0), and the player is placed on top of it (100, 49, 0, facing west). The end portal blocks emit a light level of 15—the brightest light level in game.
