Abstract:
Distances to nine dark globules are determined by a method using
optical (VRI) and near-infrared (near-IR) (JHK) photometry of stars
projected towards the field containing the globules. In this method,
we compute intrinsic colour indices of stars projected towards the
direction of the globule by dereddening the observed colour indices
using various trial values of extinction AV and a standard
extinction law.
