Right Ascension (RA) and Declination (Dec) coordinates are plotted for
equinox J2000.0. The sky map is an Azimuthal
Equidistant Projection centered on the source coordinates; distances
measured along lines passing through this plot center will be true.
Remaining distortion over the displayed 9° x 9° of sky is less than
1%.
On plots close to the Galactic plane, the Galactic equator
(b=0°), is shown as a faint dotted
line.
