Base class for the configuration and results of ranging definitions.
Ranging is a data post-processing step used in the research field of atom probe during which elemental, isotopic, and/or molecular identities are assigned to mass-to-charge-state-ratios within a certain interval. The documentation of these steps is based on ideas that have been described in the literature:

How many ion types are distinguished. If no ranging was performed, each ion is of the special unknown type. The iontype ID of this unknown type is 0 representing a reserve value. Consequently, iontypes start counting from 1.
maximum_number_of_atoms_per_molecular_ion: (optional) NX_UINT {units=NX_UNITLESS}

Assumed maximum value that suffices to store all relevant molecular ions, even the most complicated ones. Currently, a value of 32 is used (see M. Kühbach et al. <https://doi.org/10.1017/S1431927621012241>`_).
PROGRAM: (optional) NXprogram
SERIALIZED: (optional) NXserialized
mass_to_charge_distribution: (optional) NXprocess
Specifies the mass-to-charge-state-ratio histogram.
min_incr_max: (optional) NX_FLOAT (Rank: 1, Dimensions: [3]) {units=NX_ANY}
Smallest, increment, and largest mass-to-charge-state ratio value.

To begin with we use a free-text field to learn how atom probers define a background model. Future versions of NXapm_ranging can then use this information to parameterize these models.
