Table 1.
Input parameters of the variability computation.
| Symbol | Parameter | Accepted values | Default value | Function |
|---|---|---|---|---|
| DL | Detection level | ℜ+ | 10 | Level above which an area is considered as being variable. A lower value allows the detection of more sources, but a higher proportion of the detected sources will be non-variable. |
| TW | Time window | ℜ+ | 100 s | Duration of the time windows. It is also the minimal timescale of the variability that can be explored. |
| b | Box size | [3,5,…,63] | 5 | Length in pixels of the detection box, limited by the size of the CCDs. It determines the extension of the variable area that we want to detect. |
| rGT | Good time ratio | [0;1] | 1.0 | Critical (good time)/TW above which the time window will be taken into account. Choosing 1.0 will remove all time windows that have been partially or entirely contaminated by soft proton flares. |
