12 samples. Each pair has the same precinct, style and extracted votes. Look for the same paper: the shape and place of each hand mark, stamps, tears and handwriting. Pixel darkness changes from scan to scan, so it is no test. Each clip image has 00014_01677 on the left and 00014_01694 on the right. An oval is in it if its mark reaches the marginal threshold on either scan. pmv is the darkness of the oval. Clips are at full resolution, one pixel of the scan to one pixel of the image.
