Descripción
Line-of-sight velocity fields in an irregular sunspot (NOAA 8990) have
been determined from Stokes-I spectra of the line Fe I 630.15 nm,
obtained with the La Palma Stokes Polarimeter at the Swedish Vacuum
Solar Telescope on May 13, 2000. We show and discuss the resulting
velocity maps, the dependence of velocities on the continuum
intensities, and the correlation between velocities and line
asymmetries.
