For clarity, mapping the model state to the observation should be done outside the CATHY DA class.
The map_states2observations function is currently included in the CATHY DA class.
map_states2observations defined 5 operators H:
For ERT data, H is Archie law, SWC --> ER0 --> ERapp
For SWC data, H is a multiplicator (porosity)
For tensiometer data, no mapping is needed or VGP model, if the model state used, is saturation
For discharge, no mapping is needed (direct comparison with modelled discharge)
For scale data: no mapping needed (direct comparison with water balance)
Providing mapping has is own class one could use it its proper mapping relationship. CATHY DA class could inherit from the CATHY mapping class to parse it.
