NXpeak

Status:

base class, extends NXobject

Description:

Proposal for storing mathematical models of peaks, their functional form or at least their measured support.

Symbols:

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

Nsupport

Groups cited:

NXcollection

Structure:

label: (optional) NX_CHAR

Human-readable identifier to specify which concept/entity the peak identifies.

peak_model: (optional) NX_CHAR

Is the peak described analytically or empirically via intensity/counts as a function of an independent variable.

Any of these values: empirical | gaussian | lorentzian

position[Nsupport]: (optional) NX_NUMBER {units=NX_ANY}

In the case of an empirical description of the peak and its shoulders, this array holds the positions were independent variable values were taken.

intensity[Nsupport]: (optional) NX_NUMBER {units=NX_ANY}

In the case of an empirical description of the peak and its shoulders, this array holds the intensity/count values at each position.

COLLECTION: (optional) NXcollection

In the case of an analytical description this group can be used to hold parameter of the functional form. For example in the case of Gaussian peaks mu, sigma, and cut-off values and background intensity.
