Comparison of the brighter-fatter effect in the X and Y direction that are observed on CCD E2V-250, DECam and MegaCam.

| CCD E2V-250–550 nm | 1.594 | 0.047 ± 0.002 | 1.622 | 0.052 ± 0.003 |
| CCD E2V-250–900 nm | 2.042 | 0.037 ± 0.0005 | 2.048 | 0.043 ± 0.0007 |
| DECam–r-band (~640 nm) | 1.709 | 0.022 ± 0.001 | 1.944 | 0.024 ± 0.001 |
| MegaCam–r-band (~640 nm) | 1.980 | 0.005 | 1.960 | 0.006 |
Notes. Comparison between the two columns shows that the amplitude of the broadening is steeper in the Y direction than in the X direction. It should be noted that the values that are estimated for the MegaCam instrument are arguable because they depend on the range where they are adjusted.
