Summary of the main parameters in the MST source detection algorithm and their meaning.

Parameter Meaning
Λm Mean edge length in the MST built on a given field.
Λcut Cut length for the primary selection (e.g. defined as a fraction of Λm).
Ncut Minimum number of nodes for the primary selection.
N Number of nodes for a cluster.
g Clustering parameter, the ratio of Λm in the field to the mean edge length in the cluster.
M Magnitude of the cluster, defined as M = Ng.
Rm Median radius, the distance from the cluster centroid containing 50% of the photons.
Rmax Maximum radius, the distance from the cluster centroid to its farthest photon.
