Map of the photometric, residual, and total relative error bars. Top: map of the PSF fitting errors (outcome pf the Starfinder photometry) along the IRDIS FoV. Middle: map of the residual errors, outcome of the background analysis after removing the stellar source signals from the image. Bottom: map of the total relative error, combination of the PSF fitting errors and the residual background errors. Left images are in the J band. Right: images are in the Ks band.
