BTW position angle is notated as theta in degrees and separation rho arcseconds .
Position angle is measured from the line going to celestial north, and increases through east in aclockwise direction. North is the meridian at 0° position angle, east(following) is on the right at 90° position angle, and west (preceding) is on the left at 270° position angle
