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.
