A user of my software reported a large discrepancy with the USNO "Celestial Navigation Data for Assumed Position and Time" in the declination of Jupiter for 14th May. Checking revealed that the USNO data reverses the N/S Name when the true declination lies between -1.0 and 0.0 degrees, as this graph shows.
