Gemini/NIRI H-band image

Same Gemini image as in geminiann04015a (left panel), this time with positions of four other sources near the candidate object with H_AB ~ 25. These are barely visible or undetected in the VLT data shown in Figure 1 (right panel). In addition, the objects labeled “Art” are artificial sources with H_AB = 25.0. The three artificial sources were used to assess the detectability of objects with this brightness in the NIRI image.
