Finding chart for very young brown dwarfs in the Orion Nebula

This is the "finding chart" of the positions of the very young Brown Dwarfs in the Orion Nebula during a study. The star-like symbols represent the brightest stars and are plotted for reference. In this chart, very young Brown Dwarfs are represented by a double open circle (if a dusty disk was detected) or with a single open circle (if no dusty disk was detected). The sky field measures about 4.9 x 4.9 arcmin 2 (1024 x 1024 pix 2). North is up and East is left.
