8// procedures to plot the sma, emp, and cor data
9// - user interaction is through control bar on COR_Graph
10// - provides user with feedback about peak angle, transmissions
11// - asks for information about BKG and EMP levels
12// - asks for sample thickness
13// - interactively selects range of data to save (and type)
14// - dispatches to routines to determine transmissions and correct the data
15// - dispatches to save routines
