Classification criteria taken from Poggianti et al. (2009) used in this study for grouping the cluster galaxies into five pectral types according to the equivalent widths values of their [OII]λ3727 and Hδ lines.
| Spectroscopic class | EW([OII]) value | EW(HδA) value | Number |
| [Å] | [Å] | of galaxies | |
|
|
|||
| Passive | >−5 | <3 | 108 |
| Post-starburst | >−5 | ≥3 | 21 |
| Quiescent star-forming | ]−25, −5] | < 4 | 23 |
| Dusty starburst | ]−25, −5] | ≥ 4 | 14 |
| Starburst | ≤−25 | any | 21 |
Notes. The following convention is used: EW < 0 for emission lines, EW > 0 for absorption lines. The number of galaxies found in each class is given in the last column.
