IXTdataset 1d

An IXTdataset_1d is an object that stores signal and error data against one independent dimension (the x axis). Title and label information is also stored. These are used for manipulating and visualising a single spectrum.

One dimensional plotting can be used to visualise the data and many functions exist to manipulate it given in the user manual

Fields

IXTdataset_1d objects contain the following fields

Field	Description
IXTbase	Object required for internal use
title	Title of the dataset used in plotting
signal	Signal data
error	Standard error
s_axis	IXTaxis object containing the signal axis label and units code information
x	Independent variable data (i.e. x data)
x_axis	IXTaxis object containing the x axis label and units code information
x_distribution	True if signal is a distribution on x (e.g. counts/microsecond) False if signal is not a distribution on x (e.g. counts)

Constructing an IXTdataset_1d Object

The constructor for an IXTdataset_1d can be used to create a full IXTdataset_1d object

 w = IXTdataset_1d(base, 'title', [signal], [error], s_axis, [x], x_axis, [x_distribution])

• Length(signal), Length(error), Length(x) must all be equal
• signal, error and x must be one dimensional arrays
• s_axis and x_axis must be properly constructed IXTaxis objects
• x_distribution must be a logical value (1 or 0, TRUE or FALSE)
• base must be a properly constructed IXTbase object

Datasets without title and label information may be constructed using the syntax

w = IXTdataset_1d(x, signal, error)

• signal and error may be omitted. If so, w.signal and/or w.error will contain an array of 0's matching the dimensions of the x data
