Develop accurate cluster center proxies

Background: Achieving percent-level precision on the modified gravity parameter ($\alpha_{MG}$) is demanding and requires accurate modelling and mitigation of systematic effects, particularly cluster center mis-specification.

Question / Future Work: Future efforts should be invested in several strategies to accurately determine cluster centers, including: (i) exploring different averaging prescriptions for member positions, (ii) determining a cluster’s center by jointly using X-ray and optical observations, (iii) obtaining additional information via integral field spectroscopy, or (iv) adopting a statistical prior on the center location rather than fixing it.
