Plot 4) Plot the "RA (J2000) of a star" (Y-axis; min=0, max=360 degrees) vs. "Dec (J2000) of a star" (X- axis; min=-90, max=90 degrees). "RA" and "Dec" are measurements of star positions, equivalent to the "longitude" and "latitude" coordinates on a globe of the Earth, and so this plot will show you the position on the celestial sphere of all of the exoplanets discovered so far ("12000" simply refers to the precise year in which the stars were at those precise locations).
