---+ Chained Passband

A way of combining [[DataModelPassband][passbands]] for modelling a set of cumulative passbands.  For example, placing one filter in front of another would be modelled as a =ChainedPassband= containing two =FilterPassbands= .

Might be used to model the various passrate effects during transmission from source to measurement (such as atmosphere, filter, detector).  

---++ Implementation

Implements [[DataModelPassband][Passband]].

Might be implemented as a linked list of passbands, or just a pair of  passbands, one of which could be another =ChainedPassband=.
