    Those fields would be the lat/lon locations on the map associated with each point that you clicked. I'm guessing your map probably has a collar which shows the latitude and longitude values for grid lines cutting through the map, so in the middle view zoom in and click on one of those grid line intersections to provide the pixel X and Y coordinates, then enter the associated latitude and longitude values, then press 'Add Point to List'. Repeat for a few other points of known location, then press OK.
