4.8 Cross−Section Window

This window is used for displaying cross sections through the image. The window can be obtained by pressing the left mouse button in the image area.

The functions for the mar345−Cross section window widgets are as follows:

No. of peaks	Specifies the number of peaks between the two dashed lines
	in the plot area of the mar345−Cross section window. Use the
	arrows on the right hand side of the text field to increment or
	decrement the value by 1.
	When pressed, the real space cell constant is calculated from
	the distance between the two dashed lines and the number of
	peaks. The result is displayed in the message area.
Message area	Shows the coordinates of the start and end of the line, the
	angle with the base line, maximum, minimum, average and
	standard deviation of the intensities along the drawn line.
	When changing the no. of peaks manually, the second line
	displays the derived cell constant.
