The characteristic size and brightness of facular points in the quiet photosphere

By using two very-high-resolution, white-light plates of the solar granulation, characteristic size and intensity for facular points were measured. The plates were obtained with the 50-cm refractor at Pic-du-Midi Observatory by using a 60-A band-pass filter center at 5750 A. After adjustment for atm...

Description
Summary:By using two very-high-resolution, white-light plates of the solar granulation, characteristic size and intensity for facular points were measured. The plates were obtained with the 50-cm refractor at Pic-du-Midi Observatory by using a 60-A band-pass filter center at 5750 A. After adjustment for atmospheric and instrumental smearing, a characteristic size of 0.22 arc sec and a characteristic intensity of 1.3 to 1.5 times the mean continuum intensity were found.
