Table 2
Total numbers of emldetect detections with the 2D and default PSFs, and the percentage change in numbers, for various “problem” cases, and for the “random” and the “clean” samples (see text).
| Set | Problem | N | N | (2D − def)/def |
| type | (2D) | (def) | perc. change | |
|
|
||||
| Problem | non-piled-up | 4286 | 4491 | –4.6% |
| piled-up | 1171 | 1255 | –6.7% | |
| off-axis sources | 1372 | 1388 | –1.2% | |
| OOTs (piled-up) | 132 | 135 | –2.2% | |
| extended sources | 896 | 893 | +0.3% | |
| reflection arcs | 1194 | 1172 | +1.9% | |

| Problem | Total | 9417 | 9700 | –2.9% |
|
|

| Random | Total | 6395 | 6524 | –2.0% |
|
|

| Clean | Total | 2570 | 2575 | –0.2% |
Notes. Negative percentage changes indicate that the 2D PSF performs better at avoiding likely spurious sources in problem fields.
