| PR Photo 22a/01 shows a
colour composite of near-infrared images of the central regions of the
Orion Nebula, obtained on March 14, 2000, with the SOFI instrument at the
ESO 3.5-m New Technology Telescope (NTT) at La Silla. Three exposures were
made through J- (wavelength 1.25 µm here colour-coded as
"blue"), H- (1.65 µm; "green") and Ks-filters (2.16
µm; "red"), respectively. The central group of bright stars is
the famous "Trapezium". The total effective exposure time
was 86.4 seconds per band. The sky field measures about 4.9 x 4.9 arcmin2. North is up and East is left. |

PR Photo 22b/01 contains the corresponding "finding
chart" with the positions of the very young Brown Dwarfs
in the Orion Nebula that were studied during the present investigation.
The starlike symbols represent the brightest stars in PR Photo 22a/01
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 scale is
exactly as in PR Photo 22a/01. |
