Welcome to YSO standard classification’s documentation!

This Python package is used to classify young stellar objects using the standard classification scheme originally devised by Lada et al. (1984).

It determines the infrared spectral index \(\alpha_\mathrm{IR}\) in the range from \(2\,\mu\mathrm{m}\) to \(20\,\mu\mathrm{m}\), estimating the slope of the spectral energy distribution. Based on the measured slope, the YSOs are divided into 5 distinct classes (0/I, flat spectrum, II, III with debris disk, III no disk/MS star).
