1. About

ASteCA is an open source code developed entirely in Python, designed to fully automatize the usual tests applied to stellar clusters (SC) in order to determine their characteristics: center, radius, stars’ membership probabilities and associated intrinsic/extrinsic parameters: metallicity, age, extinction, distance, binarity, and total mass.

The code is designed modularly thus allowing the user to select which tests to run and which to skip, all managed through a simple input data file.

ASteCA is intended to run without the need for user intervention but both a semi-automatic and a manual mode are made available in case user input is necessary or required.
