... In 1930, Trumpler noticed that linear diameters (LD) of open clusters increase with distance (D) from the Sun. ... Since that time, the interstellar absorption has become one of the best studied factor in astrophysics, and we may hope that current OCL distance scales are free from this LD-D correlation. To verify if this is the case we have chosen several modern OCL distance scales and test them with the same clusters and the same angular diameters that Trumpler had used back in 1930. ...

Line widths measurements of the coronal ion Si VIII confirm earlier observations which show an increase in the non-thermal velocity above the solar limb. The present data taken at the equatorial limb, show an increase from 24 km s^-1 at the limb to 28 km S^-1 some 25,000 km above the limb. The electron density as measured from the Si VIII line pair show a decrease from 3.5 10^8 cm^-3 to 1.8 10^8 cm^-3 over the same distance. ...

... ROTATION CURVE: When studying spiral galaxies it is invariably found that the stellar rotational velocity in the disk remains constant, or "flat", with increasing distance away from the galactic center. ... The rotation speed of the stars in galaxies is found NOT to decrease with increasing distance from the galactic center (see emission lines in the spectrum), implying that the overall mass distribution of the galaxy is different from the light distribution. ...

This command allows a sufficient margin for usual labelling, taking into account the current size of the font. ...
