From: Performance of Akatsuki/IR2 in Venus orbit: the first year
Example of IR2 images obtained during Venus orbit. a First-light Venus image acquired with IR2 at 2.02 μm (December 11, 2015, deconvolved with the PSF described in the text). The inset is corrected for limb darkening by assuming Lambertian intensity distribution. The large-scale bow-shaped feature is hinted at although not as prominent as in LIR images (Fukuhara et al. 2017); b, c example images of the night-side of Venus at 1.735 and 2.26 μm (August 13, 2016, acquired with “night-optimized” observation). The 2.32-μm image is omitted as it appears almost identical to the 2.26-μm image
