Drift tolerance values
| . | Standard . | Acceptable . | Critical . |
|---|---|---|---|
| τstab: stabilization time | <45 min | (45–120) min | >120 min |
| Vb: mean velocity before stabilization | <15 nm/min | (15–100) nm/min | >100 nm/min |
| Va: mean velocity after stabilization | <15 nm/min | (15–50) nm/min | >50 nm/min |

| Vb: mean velocity before stabilization | <15 nm/min | (15–100) nm/min | >100 nm/min |

The drift is negligible when the velocities before and after stabilization are identical and kept under 15 nm/min and the stabilization time τstab is lower than 45 min. The drift becomes acceptable for velocities before and after stabilization in the range of 15–100 and 15–50 nm/min respectively and 45 < τstab < 120 min. For higher values the drift is considered critical and not acceptable. These values are experimental and serve to guide microscopy users to apprehend the orders of magnitude for their experiments.
