SpecValSpecVal - The spectral position at which flux values are measured

Description:
This attribute specifies the spectral position (frequency, wavelength, etc.), at which the values described by the FluxFrameFluxFrame are measured. It is used when determining the MappingMapping between between FluxFrames.

The default value and spectral system used for this attribute are both specified when the FluxFrame is created.

Type:
Floating point.
Class Applicability:
FluxFrame
All FluxFrames have this attribute.
