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.
