Table 1.
Computing time (in seconds) for different source regions (with length L in RE) and numbers of stars, N⋆.
| L | N⋆ | tPIP(tpot) | tIPM |
|---|---|---|---|
| 5 | 33 | 3 (0.35) | 17 |
| 10 | 134 | 7 (0.35) | 56 |
| 20 | 537 | 13 (0.41) | 191 |
| 40 | 2148 | 28 (0.54) | 563 |
| 80 | 8594 | 45 (1.04) | 1722 |
| 160 | 34 377 | 34 (3.03) | 6126 |
| 320 | 1 37 509 | 30 (11.0) | 23 550 |
Notes. The third column indicates the time required by our new combined approach, tPIP, the fourth column shows the time of the combined method spent for the potential calculation, tpot, and the last column provides the time required by the IPM method, tIPM.
