Supplementary materials to the paper S2D2: Small-scale Significant substructure DBSCAN Detection II. Tracing episodes and gradients of star formation activity. All materials are described in Appendix A from the main paper, which links to this repository. Includes: Additional robustness analysis. We provide a document with the results of additional tests. Relationship between distance, spatial scales and activity regime Tests on NGC2264 of the procedure to calculate relative risk Comparisons of structures retrieved by NESTs and other methods Maps: Large pdf versions of maps of each region. Spatial distribution of NESTs (such as those in the main paper) Comparison of NESTs and other retrieval method (such as those in the supplementary material) Tables with: General characteristics of regions and substructres. Members of each region along with its classification and identifier of its host NEST
