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 FluxFrame are measured. It is used when determining the
Mapping between between FluxFrames.
The default value and spectral system used for this attribute are both specified when
the FluxFrame is created.
Type:
Floating point.
Applicability
FluxFrame
All
FluxFrames have this attribute.
