The Sun in C IV and Cont.: Spectral Information

The images above show average intensities collected from 10 raster steps at the south polar limb:

• (right:) the spectral window, i.e. part of the image of the 1x300 arcsec slit on the detector, with the Carbon IV (1548 Å) line clearly to be seen, incl. limb brightening,
• (left:) the line profile, i.e. the average intensities for this window, measured in counts/arcsec²/s (log scale), vs. their 50 spectral pixels (1 px = 0.042 Å).

The spectral region considered continuum, to the right of the C IV and the two Si I lines, is marked with asterisks.
