Beginning of ReadMe : J/A+A/491/561 Plasma filling factor of coronal bright points (Dere+, 2008) ================================================================================ The plasma filling factor of coronal bright points. Coronal bright points. Dere K.P. <Astron. Astrophys. 491, 561 (2008)> =2008A&A...491..561D ================================================================================ ADC_Keywords: Sun Keywords: Sun: corona Abstract: We determine the volumetric plasma filling factor of coronal bright points. Rastered spectra of the regions of the quiet Sun were recorded by the Extreme ultraviolet Imaging Spectrometer (EIS) during operations with the Hinode satellite. Calibrated intensities of Fe XII lines were obtained and images of the quiet corona were constructed. From the imaged spectra, the emission measures and geometrical widths of coronal bright points were obtained. Electron densities were determined from density-sensitive line ratios. A comparison of the emission measure and bright point widths with the electron densities yielded the plasma-filling factor. Description: The data describe the observed and derived properties of a set of corona l bright points. The labeling allows the reader to correlate the data in Table 2 with their images in Figures 2 and 3.
