Using the polar=True option in matplotlib, the closest plot I've managed to produce is this ( MWE below, data file here ... WebbRA is the abbreviation for right ascension, while DEC stands for declination. The right ascension and declination correspond to the longitude and latitude of the Earth but refer to the sky. The equatorial grid is thus a geocentric coordinate system on the celestial sphere.
