Gallery of first and last images in SMDET input (unWISE image time series) and output (combined with ﹩\sigma ({\hat{y}}_{{\rm{seg}}})\odot {{\rm{SS}}}^{-1}({\hat{y}}_{{\rm{obj}}})﹩). Pixel values clipped below −15 and above 80 DN in input images (except for row VVV 1655) and dynamic range adjusted for output images to aid visibility.
