View Menu

Constants... Show molecular constants window. See the constants window for general information, and the objects section for more information on individual constants.
LineList... Show line list window. See the section on line fitting for more about using this window.
Log... Show log window. The contents of this window is described in the section on the log window, and more about using this window is given in the sections on line fitting and contour fitting.
Residuals... Bring up the Residuals Window that plots the observed-calculated (or other values) from the most recent fit.
Intensity Residuals... Bring up the Intensity Residuals Window that plots the observed and calculated line intensities.
Overlays... Show overlay details
States Show states of a particular J and symmetry. See the states window for more information.
Transitions Show selected transitions. More about this window is explained in the transition window section.
Levels Show an energy level plot.
Constants Plot Bring up the Constants Plot Window.
Another Plot Open another spectrum window.
Single Plot Close all spectrum plots apart from main window.
Arrange Windows Try and arrange PGOPHER windows around main window.
Bring All To Front Bring all windows in front of windows from other applications.
Windows on Taskbar Toggle display of all windows on task bar or only the main window).
Windows on Top Toggle forcing sub windows to be on top of main window.
Timing View time spent in various routines.
Memory Show memory usage.
Threads Set the number of independent threads of calculation. For simple (quick) calculations and single CPU systems leave this set to "single process" as there is some overhead associated with parallelizing the calculations. For systems with 2 or more CPU's setting the number of threads to twice the number of CPU's can result in significant speed up. It may be worth adjusting the multiple, depending on the nature of the calculation.
Clear Log Clear log window.
Clear Cache Clear any saved calculations. This can be useful to prevent PGOPHER using too much memory, and may be required if a calculation fails.
Clear Observed Clear observed line marks from plot.
Calculator Simple calculator for testing expression evaluation.
Text Size Scale text throughout application - useful for demonstrations using a computer projector. The menu text is not currently affected.
