Once the data file has been created
or loaded (File, Open or or simply drag and drop a .pgo file onto the main
window) simply press the red simulate button
if a simulation does not appear
automatically. To change the molecular parameters use the Constants Window. The buttons listed
below can be used to adjust the appearance of the plot. The
Offset, rotational temperature (T), and the Gaussian (Gau) and
Lorentzian (Lor) contributions to the linewidth can also be changed
using the boxes in the
main window. The items below are available as buttons on the toolbar or
