< 0.5 sebagai galaksi tidak bercantum dan galaksi dengan P _{M E RG} > 0.8 sebagai yang bercantum. Data Hα dan peta kelajuan Hα diperoleh daripada MaNGA DR15 manakala data HI diperoleh daripada katalog HI-MaNGA DR1 untuk kesemua 60 galaksi. Tujuh belas daripada 30 galaksi bercantum mempunyai lebih daripada satu tompokan Hα (28.3% daripada 60 galaksi) berbanding 14 daripada 30 galaksi tidak bercantum (23.3%). Empat belas daripada galaksi bercantum (23.3% of 60 galaksi) mempunyai taburan kelajuan Hα tidak simetrik berbanding 8 galaksi tidak bercantum. Tiga belas daripada galaksi bercantum mempunyai puncak HI (21.7%) berbanding 11 galaksi tidak bercantum (18.3%). Hasil kajian mendapati data Hα dan HI menunjukkan potensi sebagai penanda berlakunya aktiviti percantuman galaksi.
