The file E-D56Clusters.fits is a FITS table that combines the information from Tables A1-A3 in the ACTPol two-season cluster catalog paper. It can be viewed with any compatible viewer, e.g., TopCat, or read into Python using the astropy.table module.
The columns contain the following information:
| column name | description |
| name | Name of the cluster |
| RADeg | J2000 right ascension of the cluster in decimal degrees |
| decDeg | J2000 declination of the cluster in decimal degrees |

| SNR2p4 | Signal-to-noise ratio at the reference 2.4 arcmin filter scale |
| y0tilde | Cluster central Compton parameter measured at the 2.4 arcmin filter scale (x 10-4) |
| y0tilde_err | 1-sigma uncertainty on the cluster central Compton parameter measured at the 2.4 arcmin filter scale (x 10-4) |
| H13Match | 1 if the cluster is matched to an object in the Hasselfield et al. (2013) ACT equatorial cluster catalog; 0 otherwise |
| PSZ2Match | 1 if the cluster is matched to an object in the Planck 2015 PSZ2 SZ cluster catalog; 0 otherwise |
| RMMatch | 1 if the cluster is matched to an object in the redMaPPer v5.10 cluster catalog (Rykoff et al. 2014); 0 otherwise |
| AltName | Alternative name for this object (generally the closest match listed on NED) |
