To mitigate the indexing issues that can arise in situations where data is loaded incrementally, \code{gadfly} performs an intermediate step, first loading new fields into a \code{pandas.Series} data structure, using the particle ID numbers as an index. This allows \code{pandas} to properly align the particle fields, dropping any particles not in the existing \code{PartType} dataframe from the newly loaded field as it is appended.  This approach, which can be used in tandem with the refinement index, affords \code{gadfly} the flexibility needed to allow incremental manual refinement of the data stored in memory.   Additional cuts can be made as subsequent fields are loaded, resulting in the selection of a precisely targeted primary dataset from which derived properties (e.g., temperature) may be calculated, serving which serves  to reduce computational overhead as well.
