Package PSHist

PSHist packages contains a set of classes providing abstract interfaces for histogramming service. Specific implementation (e.g. based on ROOT) is instantiated by psana at run time, but client code is supposed to interact with the histogramming service only via abstract interfaces from this package.

Package PSTime

This package include several classes and functions which define time representation and operations with time. It is based on on standard ISO8601 external representation (http://en.wikipedia.org/wiki/ISO_8601) but it does not provide complete support and in some cases it is made more human-oriented.
