[esp-r] Re: Is there any documentation on plant components?

[Denny Beyer]

Documentation on plant systems is not very comprehensive at this stage.
As been said already, you find descriptions of plant components in the 

* Source Code. 
In folder "esruplt/"
Most components are implementet in files called "pcompX.F" (X = 1...4) and 
additional data in pcomps.F.
Some newer components are placed in separate files and can be indentified by 
their name.

* PhD Thesis
Hensen J L M (1991)
Aasem E O (1993)
Kelly N J (1998)

You will find all for download on the ESRU website in the Publications 
section.
