The KASCADE primary energy spectra don't describe the
GAMMA experiment EAS data set.
Below the detected EAS size spectra and EAS
muon truncated spectra are presented (2005)
for SIBYLL and QGSJET interaction models.
The black lines are our predictions according to primary spectra from
0704.3200 [astro-ph] (2007).
The red lines are the corresponding predictions according to
the KASCADE primary spectra.

CONCLUSION: The KASCADE primary spectra disagree with
GAMMA data set
(presented in 29th ICRC, Pune, India 2005)
We explain the observed disagreement by the very flat
(energy spectral
index is about -1.9) KASCADE's Iron energy spectrum
due to pseudo solutions
0706.4087 [astro-ph] (2007).
