Notes:
[1] BOLD indicates an HQ value greater than 1.
[2] Figures for HQ_ERPG1s were not created because in these situations the unrefined HQ_ERPG1 values are less than the HQ_AEGL1 values and after refinement all the HQ_AEGL1 values were less than 1 so the HQ_ERPG1 values would also be less than 1.
