Map of the signal-to-noise ratio, relative to the ADI-like reduction described in Sect. 3.2.3 on the 26-11-2021 IFS observation of HD 34700 A. The central blue circle masks the area within 1.3 λ/D, where self-subtraction is significant. The colourbar indicates the S/N level. A couple of higher-S/N points on the western side may be spurious speckles; no reliable point-source is detected in this reduction. North is up and east to the left.
