You might want to take a look at the Density chapter in the "Calibre Solutions for Physical Verification" manual. This ships standard with the documentation. (Look for "calbr_solns_pv_user.pdf") If the explanations there are not detailed enough, it has links to the various commands which should have more detail. Failing that, customer support may be able to answer specific questions.
