Table 1.
Mean computation time over the 300 runs and the mean variance over four different ranges of r bins (given in units of h−1 Mpc) for each method.
| Method | Time | Mean variance |
|||
|---|---|---|---|---|---|
| [s] | 0–2 | 5–15 | 80–120 | 150–200 | |
| [×10−2] | [×10−5] | [×10−6] | [×10−7] | ||
| Mr = 50 | 7889 | 1.01 | 4.42 | 1.23 | 7.01 |
| Mr = 25 | 2306 | 1.01 | 4.39 | 1.23 | 7.04 |
| Mr = 1 | 16.5 | 5.96 | 5.53 | 1.46 | 8.05 |
| d = 0.5 | 2239 | 1.01 | 4.41 | 1.25 | 7.11 |
| d = 0.25 | 812 | 1.02 | 4.41 | 1.25 | 7.42 |
| d = 0.14 | 487 | 1.08 | 4.41 | 1.28 | 7.72 |
| Ms = 4 | 1854 | 1.01 | 4.42 | 1.23 | 7.02 |
| Ms = 16 | 763 | 1.00 | 4.42 | 1.23 | 7.01 |
| Ms = 50 | 593 | 1.09 | 4.42 | 1.23 | 7.02 |
Notes. The first three are standard LS. The variance cannot be measured accurately enough from 300 realizations to correctly show all the differences between methods. Thus the table shows some apparent improvements (going from Mr = 50 to Mr = 25 and from Ms = 4 to Ms = 16), which are not to be taken as real. See Fig. 6 for the fifth vs. second column with error bars.
