Example detections for known MBAs that have at least three previously unreported observations. Images show subframes of registered WISE images after SALTAD processing. Black and white images show the object in individual frames whereas the image in color shows the shifted and stacked image of the object, where the color conveys the number of standard deviations above the noise. We stack the images by summing the signal in each frame and dividing by the sum of squares of the noise for each frame. Red dots are located at the SALTAD detection centroid, an orange “+” appears at the location of the HORIZONS ephemeris, and a blue “x” is at any locations previously reported by the NEOWISE team. The annotations at the bottom of each frame report the S/N of the central pixel only, which is not equivalent to the MLE dB of the true hit, which is listed at the top.
