Figure 1
Selection of suitable isolated crystals for data collection. If two crystals are closer than a pre-defined threshold distance (in this case 1.2 µm), they will be both labeled not isolated. Among the three crystals found in this figure, two of them (at the centers of the red circles) are too close to each other (within the 1.2 µm area). Therefore, only the crystal inside the blue circle passes the criteria for data collection. Any crystal inside the red masked region is considered to be too close to the edge of view, and is first moved to the center using stage translation before applying the selection criteria again. Both thresholds can be tuned.
