This small window tracks the current cursor position in several sets of units: the (x,y) coordinates of the data array, the q-value ((4 pi / lambda) sin theta), 2theta, and chi. Nothing is shown if no data have been read in.

Note that the angular and q values are meaningless if the image has not been calibrated. Note also that, depending on the operating system and hardware used, the tip of the cursor may not lie exactly over the pixel reported.
