Table 3.
Residual maps of the lens modelling, i.e. normalized χ2 per pixel.
Notes. The maps corresponds to (fmodel − fdata)/σ, where fdata is the observed flux, fmodel is the modelled flux and σ is the estimated rms noise level at the pixel position. The color map ranges from −6σ (blue) to +6 σ(red). The given χ2 value in each panel is the mean χ2 per pixel and does not include the time-delay information.
