Private analysis code should always go to the file RELEASE2/src/mail/mo.C. The class mo is a public derivative of moBase, and therefore inherits all properties of it.
After starting 7of9 via BorgTransmitter, an object of mo is instantiated automatically. You can access it in 7of9 via m. For example:
m->BXov("2000/06/01", "2000/07/10 13:20") gives you an overview plot of the bunch database for the given time interval.
m->makent("demo", "1999/01/01", "2000/09/01") creates a ROOT-Tree (stored as RELEASE2/rootnt/seven_demo.root) including all the relevant target information of the last two years.
m->ThisIsMyStuff() calls your private analysis method mo::ThisIsMyStuff().
