Table 1.
Description of the completeness functions introduced in Sect. 3.
| Symbol | Description |
|---|---|
 |
Completeness of the ith colour condition, |
| given a set of sampled parameters. | |
 |
Completeness derived through the combination |
| of all the optimal colour conditions. | |
| Cnf | Completeness given by the combination |
| of a subset of optimal colour conditions. | |
| C | Completeness obtained from a subset of optimal |
| colour conditions fitted as a function of zl. | |
Notes. Analogous descriptions hold for purity and foreground failure rate. The nf superscript represents quantities derived from colour conditions not fitted as a function of zl. Optimal colour conditions satisfy the thresholds on purity and completeness, and provide maximal completeness.
