Speed Extrema
The Speed Extrema study finds when a body reaches a maximum or minimum longitudinal speed.
Creating a Speed Extrema Study
To create a Speed Extrema study:
- Click Mundane Studies → Longitudinal Studies → Speed Extrema on the menu bar.
The new study opens with the workspace's default settings, ready to configure. You can also create it from the study-group dropdown button on the main toolbar.
Events Captured
A speed extremum occurs when a body reaches a maximum or minimum longitudinal speed. Each event marks a point in the study's date range where a selected body's longitudinal speed reaches a local peak or trough.
An Event Type dropdown controls which extrema are captured: minima, maxima, or both.
