Boolean columns

Boolean columns cannot be used in the extraction of images, spectra/histograms, and rate curves and, thus, will not be shown with associated check buttons. To the right of the pushable button with the name of the column are two linked check buttons labeled “true” and “false” corresponding to the two possible values. Only one value can be selected at a time and pushing the column button shall append either of the sub-expression
to the global expression in the top expression entry field.
