Statistics on the solar spectrum suitable for the study of the blanketing effect in stars of spectral types F, G and K

A complete set of statistics useful to the study of the blanketing effect in stars of spectral type F, G and K have been obtained on the basis of the solar spectrum.

In the spectral range 2250 Å-6400 Å the following distributions have been derived: distribution of lines with chemical elements, percentage of lines originating from ionized atoms, distribution of lines with the excitation potential and with the oscillator strength. Also the distribution with the equivalent width has been obtained in the range 3060 Å-6400 Å.

With these distributions, samples of lines have been derived for intervals of about 200 Å in the range 2250 Å-6400 Å.

Evaluations for the spectral density of lines and the percentage of non-overlapping lines are also included.
