necessary for the different reduction steps. These windows are popped
up by pushing the three-dots
button corresponding to
each calibration and reduction step on the left-hand side column of
the Main Panel. These windows contain text fields, option menus and radio buttons.

or selecting an option by clicking on the relevant button. Push-buttons
yielding to a dialog window are indicated by three dots in the label.
