Objective parameter curves of the max_ parascan( ) algorithm for each motor, where dots indicate scan points: (a) normal part of the coarse scan; (b) part of the coarse scan that may appear when the motor is stalled by a stopper; (c) the fine scan, which starts at the rightmost point where the objective value rises above a first threshold in the coarse scan, and stops when the objective value falls below a second threshold; (d) the final move to the peak position, deemed by the algorithm as the centre of the interval in the fine scan where the objective values were above the second threshold; (e) intervals skipped by the fine scan to save time. |
