Table 1
Performance of the WDS detection compared to a direct detection (DD) in terms of SNR at which at 95% of the simulated features are detected.
| Feature size | SNR at 95% detection rate | |||

| [ FWHM ] | WDS detection | DD | ||

| kd = 5 | kd = 4 | kd = 3 | kd = 4 | |

| FDR | 0 | 0.01 | 0.1 | 0.03 |
Notes. Results are obtained for features with sizes of 0.2, 0.5, and 1 FWHM of the beam and for different detection threshold factors kd. The bottom row of the table shows the mean false-detection rate (FDR) found in each test.
