| | 9 | The plot above shows 4 GPC1 images placed on the sky in relation to nearby bright stars. The largest circles are 6th magnitude, while the smallest are 10th magnitude in i-band. The sequence of four exposures start with 108o oriented north-south, shown in black. The next exposure (109) is in red; the next (110) is in black and rotated further; the last (111) is shown in blue. |

| | 13 | The following 4 images show the greyscale version of the exposures shown above. Some mental juggling is needed to compare the figure above and the images. The images have chip 00 in the upper-left, and 70 in the upper-right. It is possible to identify the stars that are causing the main glints, as discussed below. |
