A high spectral resolution is invariably an important parameter for accurate vector magnetic field measurements and faster cadence is required for the study of dynamical evolution of structures (e.g., solar flares, sunspots etc).
A high mission cadence is required to maintain and develop competence in mission design, management, and execution and, for an exploration-driven organization, to develop and train the next generation of leaders: the time between missions must be short enough that careers span the complete life of more than a few missions.
It is well known that automotive industry requires high production cadence as well as high products quality.
The extremely sensitive single photon detectors can also be re-purposed for other terrestrial and astronomical observations requiring an exceptional cadence and narrow FoV.
Beside the assumed metabolic cost of rotating the legs, extra costs may occur because high cadence requires additional muscle activity for coordination.
The advantage of the four functional measures examined within this study is that they are readily available, and require little dedicated equipment (for example, for the PFIT-s a stopwatch is required for marching in place cadence, or gait aids/chairs if required for ambulation/sitting out of bed components of all functional tests).
However, the polarimetry and the Dopplermetry are also important and they are required to be carried out in parallel with the high-cadence imaging at the Hα center.
For Solar Orbiter, the combination of an exciting new viewpoint of the Sun, and the best resolution of the corona ever seen, means that we require the best time cadence and velocity information that we can get.
Maximal and normal walking speed and cadence was measured over 10 m; gait aids were used as required and a 2 min rest was given after each trial.
To detect the impact polarization, high-cadence imaging polarimetry with the precision of the order of 0.1% is required.
