User's Guide for all versions of CPO
-that is, the User's Guide for CPO2D, CPO3D and the space-charge versions CPO2DS and CPO3DS, which is also contained in the Word 6 file 'guide.doc'
This is the traditional 'hard copy' Users Guide, giving a concise account of the main features.
This traditional form is preserved here because it is useful for new users, but please note that all the contents of it can also be found in the general Help, usually in a more detailed form. There is therefore some repetition of material.
