Querying Sys tables - Calculation Views

Soooo....

I've been playing around in the system views and found quite a bit of useful stuff for querying meta-data around base objects.

For Tables, column definitions, constraints etc ...

For Attribute views, column names, dependencies, joins & join conditions....

Yet for Calculation Views; I'm drawing a blank.

Ok, so I can list them (name, type) from sys.objects, but I've not been able to gain any further info.

Does anyone know (a) why this is (they they are not detailed in sys views ?) and (b) does the data I'm looking for exist in tables elsewhere ?

Just for illustration, a small example of the views I've been hitting so far ..
