Overview of the 
data vector choices and their relative constraining power.
| Choice | Figure | rel. FoM | nd |
|---|---|---|---|
| All combinations | 4 | 1.00 | 775 |
| Only equal zph-bins | 4 | 0.68 | 175 |
| θap ∈ {4′,8′,16′,32′} | 4 | 0.92 | 215 |
| θap ∈ {4′,8′,14′,32′} | 5 | 0.92 | 215 |
| θap ∈ {4′,14′} | – | 0.87 | 145 |
| θap ∈ {4′,14′,32′} | – | 0.89 | 180 |
| θap ∈ {4′,6′,8′,10′} | 5 | 0.88 | 215 |
| θap ∈ {10′,14′,18′,22′} | 5 | 0.72 | 215 |
| θap ∈ {22′,26′,32′,36′} | 5 | 0.55 | 215 |
| All equal-filter radii | – | 0.92 | 425 |
| Best 100 elements | – | 0.80 | 100 |
| Best 215 elements | – | 0.89 | 200 |
Notes. For the measurement of the relative FoM the individual FoM is divided by the FoM of the 
of the ‘all combinations’ case. From the second row onwards, only equal-scale filter radii are used.
