If this node is placed on the schematic as the result of a wizard, it will be called one of the following,
depending on what data is represented by the DataSource node:
• Background – the stored data represents a background light capture
• Ref – the stored data represents a reference light capture
• BkGnd – used in a Raman wizard when the stored data represents a background light capture (either
with or without laser light, depending on experimental setup).
Delta x (Delta x)
Outputs the wavelength distribution function for the input data array.
Location: Advanced Math -->Array Math --> Delta x
Number of Inputs: 1
Type of Inputs: array
Type of Output: array
User Controls: N/A
Notes:
Delta x is a function that determines how many nanometers a given pixel represents.
Delta x is expressed as a graph with units of nm/px on the y-axis and nm on the x-axis.
Derivative -- spatially based (Deriv)
Calculates and outputs the spatially based derivative of the input data array.
Location: Advanced Math-->Calculus --> Derivative
Number of Inputs: 1
Type of Inputs: array
Type of Output: array
User Controls: Select derivative order number
Notes: Pass data through a SubRange node first to differentiate over a specific wavelength range
