Intend to look at the properties below in 2-3 SAMs; few hydro runs, HOD:
- BCG mass vs halo mass
- radius
- age
- metallicity
- star formation rate (SFR)
- close companions?
- Brightness difference between first and second brightest galaxy (M1-M2)

g-r colours are similar to those observed in SDSS (von der Linden+2007)

stellarmass_SFR copy.pdf

SFR are similar to observed

stellarmass_radius copy.pdf

radii are similar to those observed (Jimmy+2012)

---

st_age_metallicity copy.pdf

- ages are similar in range to those observed in similar mass clusters (Oliva-Altamirano+2015)

- however, metallicities are significantly different.

stellarmass_Z copy.pdf

- range of metallicities and stellar masses much wider than observed

stellarmass_dominance copy.pdf

- dominance > 2 is regarded as extreme and seen in only 7% of LOCUSS clusters (Smith+10)
