NAME: thm_part_remove.pro PURPOSE: Remove bins that fall below a specified # of counts from any 3D particle data structure. CALLING SEQUENCE: thm_part_remove, dist, threshold=threshold, [/zero], [/remove] INPUT ARGUMENTS: dist: Particle distribution(s). Can be single or array of structure(s) or pointer(s) to structure(s). threshold: The value below wich data points will be removed or zeroed. Must be in the same units as the input data. KEYWORDS: zero: (default) Data below the threshold will be set to zero. remove: Data below the threshold will be removed. Specifically, the data will be set to NaN and the bin flag set to off. NOTES:
