Example of a multiple source with central multiple main objects (these images are available in our web-based graphic user interface). Left: low-resolution OTELO_deep image. Right: HST I-band high-resolution image. Ellipses in red (object in question) and green (neighbouring sources) show Kron ellipses from OTELO_deep image for individual OTELO sources. The red ellipse shows the Kron ellipse corresponding to the source id:2146, inside which two additional sources (or well defined parts of a single galaxy) are visible. This particular source has three matched sources from HST image.
