"ObservableAxis" class

Description

Owner: CharacterisationDM

The UCD characterising the observable axis tells us the nature of the measured/simulated parameter : flux, counts, polarisation parameters ( Q Stokes, etc.), velocity, metallicity, etc ... The flux case is the usual one, but all other ucd corresponding to the observed quantity will be valid.

It specializes the class CharacterisationAxis.

It contains the following operations:

"getCalibrationParam" operation

Depending on the nature of this axis, this method retrieves the calibration function that maps recorded values into interpretable physical measurements. For instance: luminosity from counts, velocity from pixel values, etc...
