Abstract

Column density (NH) and extinction (AV) values are sample of YSO sources in the ONC. Near-infrared colours based on the VISION (Meingast et al., 2016A&A...587A.153M) catalogue were employed to calculate extinction values using the NICER algorithm (Lombardi et al., 2001A&A...377.1023L) and assuming RV=3.1. Column densities were adopted from the COUP (Getman et al., 2005, Cat. J/ApJS/160/319) catalogue. In addition to NH and AV, the following quantities are provided: JHK_s magnitudes, taken from the VISION catalogue; spectral types, adopted from the catalogue by Hillenbrand et al. (2013, Cat. J/AJ/146/85); intrinsic near-infrared colours, deduced from spectral types and data by Scandariato et al. (2012A&A...545A..19S); and the YSO classification, based on the classification by Megeath et al. (2012, Cat. J/AJ/144/192). 1-Sigma error estimates are given for all quantities in the table. (1 data file).
