  11. First Lab • Sloan Digital Sky Survey (SDSS) • Coordinates: Equatorial, decimal degrees • Magnitudes: u, g, r, i, z

  12. Celestial Coordinates - Equatorial • (Right Ascention) is the angle around from the Vernal Equinox • d (Declination) is the angle above (+) or below (-) the celestial equator

  13. Modern definition of magnitude is based on light flux Note that this compares two stars. If a “zero point” is defined then where C is the zero point offset
