Abstract
Embedded clusters are groups of stars which have not dispersed yet the residual of the parental cloud where they were born, thus getting precise distances and properties ofthese groups is an essential task. We present results for five embedded clusters: [DBS2003]5, [DBS2003]60, [DBS2003]98, [DBS2003]116 and [DBS2003]117, obtained from a combination of deep CCD UBVI photometry suitable to identify blue faint stars and infrared information from available surveys. The photometry was linked with proper motions and parallaxes from Gaia DR2. Each object was treated in a multi-space using ASTECA, a code especially designed to perform an automatic data analysis and aimed at providing the fundamental parameters of star groups, in case they compose a cluster.
