Charts in the blog entry were from online. Use of these measurements were suggested to me by a reader comment in the Basis Peak blog about the sleeping heart rate plateaus, although as far as I know I am the first to formalize and systematically use them.

Molpro is a complete system of ab initio programs for molecular electronic structure calculations. It's a five star item. There is no stability in heart rate during that interval according to the Peak.

Note that January 7 was different than the other days; I comment later here on what happened that day.. Included are specialised storage methods, methods for histograming, curve fitting, function evaluation, minimization etc.
