The lower the value of the Absolute Magnitude, the brighter the object is. Absolute Magnitude and Luminosity Luminosity is the energy a star pumps out every second. The lower the star's absolute magnitude, the more luminous the star is. For instance, in Sirius, the star's absolute magnitude...

The purpose of this calibration is to obtain data on flux standards through WF/PC. These stars are 9 - 14 magnitude. This proposal replaces previous proposals ABSOLUTE UV CALIBRATION (1322) and ABSOLUTE FLUX STANDARDS (1331). Two brighter target stars have been added. Pick the brightest star...
