Table A.1.
Calibrated colour selection based on griz photometry. The listed colour conditions are combined through the ∨ logical operator.
| Colour condition | Parameters | zl range |
|---|---|---|
| (g − r)< s (r − z)+c |  ; 
|
[0.2, 0.7] |
| (g − r)< s (i − z)+c |  ; 
|
[0.2, 0.8] |
| (r − i)> c | c = 1.28 zl + 0.11 | [0.2, 0.6] |
| (g − r)< s (r − i)+c |  ; 
|
[0.2, 0.6] |
| (r − i)< s (r − z)+c |  ; 
|
[0.2, 0.8] |
| (g − i)> s (i − z)+c | s = −9.17 zl + 3.24; c = 7.07 zl − 0.45 | [0.2, 0.3] |
| (g − i)< s (r − z)+c |  ; 
|
[0.2, 0.8] |
| (g − z)< s (r − z)+c | s = 1.70; 
|
[0.2, 0.7] |
| (g − r)< s (g − z)+c |  ; 
|
[0.2, 0.7] |
| (g − r)< c | 
|
[0.2, 0.5] |
| (r − i)> s (i − z)+c |  ; 
|
[0.2, 0.5] |
| (i − z)> c | 
|
[0.2, 0.6] |
| (g − z)> s (r − z)+c | s = −0.58 zl − 1.42; 
|
[0.2, 0.5] |
| (g − i)< s (r − i)+c | s = 0.24 zl + 1.53; c = −0.91 zl + 0.33 | [0.2, 0.6] |
Notes. In the first column, the colour conditions are listed. The parameters of such conditions are shown in the second column, while in the last column the zl ranges are listed. From top to bottom, the ith row corresponds to the ith iteration of the iterative process described in Sect. 3.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
