Figures showing a small asymmetry in the M32 nucleus. Left: the model-subtracted F555W image oriented with N up and E to the left. Black solid lines show the annulus with major axes of 0 45–1 8, while the dashed line separates the northern and southern halves of this annulus. Right: comparison of the residuals of the model-subtracted images. The Y-axis plots the difference in flux between the southern and northern annuli in the model-subtracted images normalized by the original image. A 1%–2% excess in the southern annulus is seen in all bands from 0 45 to 1 8 (2–7 pc).
