| Filter | ND + NB2.17 | K s | K s |
| Objective | S13 | S13 | S13 |
| tint (s) | 30 | 24 | 24 |
| Nframe × Nexp | 2 × 1 | 4 × 8 | 4 × 8 |
| tint [sky] (s) | 30 | 24 | 24 |
| Nframe × Nexp[sky] | 2 × 1 | 4 × 1 | 4 × 1 |
Notes. The individual integration time (tint), the number of frames (Nframe) averaged by the detector and the number of repeated exposures (Nexp) are reported on source and on sky. At the end, Nframe × Nexp gives the number of images available for the data reduction and analysis.
