Lower Size Limit

Lower Size Limit

If the area of a "blob" is too small, then it may represent noise rather than a particle, a particle on the edge of the light sheet, or perhaps just a very small particle. The lower size limit specified by this option allows two different ways of treating small particles, to either ignore them, or just treat them with caution.

Lower limit for particle size (pixels area) ?

This entry palces the lower size limit on a normal particles in terms of the number of pixels occupied by that particle.

If smaller then Ignore or treat with Caution ?

Responding <I> will cause blobs with an area smaller than the size limit to be ignored, while <C> allows the blob to still be treated as a particle, but suffering a premium set by [qPR Premium if particle too small].
