Description
The data used in the publication consist of a set of CaII H spectra
taken near and beyond the solar limb on 25/08/2009 at UT 08:43-09:15.
The data were obtained with the POLIS instrument at the German VTT. The
wavelength range covers the core and the blue wing of the CaII H line
from 396.332nm to 396.969nm in 326 steps of 1.96pm. The observations
were done by moving the solar image across the slit of the spectrograph
with a step width of 0.3-arcsec, yielding in total 134 slit spectra of
326 wavelength points on 244 CCD rows along the slit. The spatial
sampling along the slit was 0.3-arcsec. The center of the field-of-view
was located at (x,y)=(+37",+920") relative to the center of the solar
disk. The data have been corrected for stray-light with the methods
described in the article and are normalized to the continuum intensity
on disc center. The corresponding data file data.fit is organized as
floating array (x,y,wavelength)=(134x244x326) pixels.
