If there are no arguments, then a dialog box opens allowing the user to enter the desired value. If there is an argument, NUTS attempts to use the argument as a number to which the current value for the zero order phase correction. If there are no arguments, then a dialog box opens allowing the user to enter the desired value. If there is an argument, NUTS attempts to use the argument as a number to which the current value for the first order phase correction. If this command has no arguments then the values currently stored with the PA and PB commands are used for the pahse correction.
Recent modification allows setting also of a second-order phase parameter, using a third argument.
This command enters a subroutine which allows the user to phase the spectrum using the mouse and based on two regions of the spectrum. These regions are selected while in the Zoom subroutine with the 1 and 2 commands. When entered, this subroutine displays and phases region one when the left mouse button is depressed and displays and phases region two when the right mouse button is depressed. This command takes no arguments. This command enters a subroutine which allows the user to phase the spectrum using the mouse.
