Status:

base class, extends NXobject

Base class for describing a peak, its functional form, and support values ...

Base class for describing a peak, its functional form, and support values (i.e., the discretization (points) at which the function has been evaluated).

Symbols:

The symbols used in the schema to specify e.g. dimensions of arrays.

dimRank: Rank of the dependent and independent data arrays (for multidimensional/multivariate fit.)

Groups cited:

Human-readable label which specifies which concept/entity the peak represents/identifies.

total_area: (optional) NX_NUMBER {units=NX_ANY}

Total area under the curve.

data: (optional) NXdata
