Not really. Ten minutes of googling didn't find anybody pointing a high resolution instrument at HD 84406, just sky surveys. From this comment https://news.yco

Not really. Ten minutes of googling didn't find anybody pointing a high resolution instrument at HD 84406, just sky surveys. From this comment https://news.ycombinator.com/item?id=30093849 https://news.ycombinator.com/item?id=30093849 here's one square degree (3600 square arcminutes) of sky around the star: https://bsrender.io/sample_renderings/hd84406-1deg-m18-ax1000-ao127-2k.png https://bsrender.io/sample_renderings/hd84406-1deg-m18-ax100... If the published calibration image is a single NIRcam exposure, then it's a 2.2x2.2 arcminute square around the central star, or, at the scale of the Gaia photo, a 33x33 pixel box. The Airy disk pretty much takes up the whole thing at that scale. You can also take a look via CDS portal: http://cdsportal.u-strasbg.fr/?target=HD%20%2084406 http://cdsportal.u-strasbg.fr/?target=HD%20%2084406 Various sky surveys also show little detail at 2.2 arcmin.
