Description of the columns of the MAGIC group catalog.
| Col. name | Description |
|---|---|
| MGR_ID | MAGIC group ID |
| RA | Right ascension (J2000, degrees) of the unweighted barycenter of the group |
| DEC | Declination (J2000, degrees) of the unweighted barycenter of the group |
| RICH | Number of members within the group |
| Z | Mean redshift of the group |
| SIGMA | Velocity dispersion σg (km s−1) of galaxies in the group, using the Gapper method |
| LMVIR | Virial mass MVir in log (M⊙) |
| R200 | R200 radius (kpc) |
| CGR_ID | Group ID in the zCOSMOS 20k group catalog (Knobel et al. 2012), when matched |
| CW_ID | Group ID in the COSMOS Wall group catalog (Iovino et al. 2016), when matched |
| XRAY_ID | Group ID in the X-ray group catalog of Gozaliasl et al. (2019), when matched |
| XRAY_SEP | Angular separation (arcsecond) between MAGIC and X-ray (Gozaliasl et al. 2019) centers |
| XLM200 | Mass at radius R200 in log (M⊙) inferred from X-rays (Gozaliasl et al. 2019) |
| XR200 | R200 radius (kpc) inferred from X-rays (Gozaliasl et al. 2019) |
Notes. Velocity dispersion σg, radius R200, and Virial mass MVir are only provided for groups of more than five members. The properties are described in Sect. 4.2.
