Top: NIRCam image in the F164N filter. The red circle corresponds to the aperture used to extract the companion’s SED (on-source SED). The orange circle, placed at the opposite of the companion with respect to the star, represent the apertures used to estimate the SED of the stellar PSF + background nebula. The green circle corresponds to the aperture of the background nebula SED. The radius of these apertures is 0.08”. Bottom: In red, On-source SED. In orange, SED of the background nebula + stellar PSF. In green, the SED of the background nebula emission.
