About These Units
Spherical Quadrant (quadrant)
A spherical quadrant equals π steradians (≈3.142 sr)—one-quarter of a complete sphere. Equivalent to two octants or half a hemisphere. Represents the solid angle of one "quarter" of the sky bounded by two perpendicular great circles.
Nanosteradian (nsr)
A nanosteradian (nsr) equals 10⁻⁹ steradians or about 42.5 square arcseconds. Used in precision optical measurements, astronomical source size calculations, and high-resolution imaging system specifications. Individual pixels in space telescopes may subtend nanosteradians.
