HD 1160 B Archives - Astrobiology

Left panel: A single frame of data from the 3.69 μm wavelength channel, overplotted with the apertures and annuli used to obtain flux and background measurements for the host star HD 1160 A (in orange) and companion HD 1160 B (in purple). The dashed lines indicate the background annuli. Each image uses a different arbitrary logarithmic colour scale, and both are north-aligned, where north is up and east is to the left. Right panel: the final LBT/ALES+dgvAPP360 image of the HD 1160 system from the second night, produced by taking the median combination of all frames in the 3.59-3.99 μm range over both time and wavelength. This image covers a total integration time of 10800 s (3 h). -- astro-ph.SR
