Caption: Figure 1.

(a) Final PISCES Ks-band image of the HD 15115 debris disk, in units of mJy arcsec ⁻², with north up, east left. The white dot marks the location of the star and represents the size of a resolution element at the Ks band. For display purposes a 0 farcs 8 radius mask has been added in post-processing. The western side SB is ~a magnitude arcsec ⁻² brighter than the eastern side SB, as is seen at shorter wavelengths (Kalas et al. 2007; Debes et al. 2008). (b) SNRE map of the image. The eastern side is detected at SNRE ~ 3 out to ~2 farcs 1. The western side of the disk is detected at SNRE ~ 3–8 from ~1 to 2 farcs 5.
