'''
Produces 3 figures for manipulation of LRM images:
image_fig, imaxes -- figure and axes objects associated with LRM output image (TIF, fit format). The image plot within
imaxes is named image, while the array used for generating the plot is imdata.
xsection -- figure containing cross section along a line through the diameter of the integration ring. Points of the line are chosen by
shift + clicking (also resizes/repositions circle). Shift + clicking within this figure will draw an additional
line for indicating the background noise level.
result_fig -- figure displaying cross section after subtraction of background noise.
