Recently, TRACE
(Lenz et al., [1999]),
Aschwanden et al., [2000]; Chae et al., [2002];
Testa et al., [2002])
and SOHO/EIT (Aschwanden et al., [1999]; Neupert et al., [1998])
focussed on 1 MK loops.
- nearly flat temperature profiles along the length of the loops,
with T @ 1.3 MK.
-
nearly flat but high emission measures
-
results are in stark contrast with predictions of
hydrostatic models
Intense debate on the subject
Reale & Peres, [2000]; Aschwanden, [2002];
Martens et al., [2002]; Schmelz, [2002]).
I have re-analysed the TRACE and CDS data and found:
- Background-foreground emission has been
neglected or treated improperly in all cases.
-
Loop densities and temperatures were overestimated.
-
TRACE and CDS observations were of different types
of loops, no comparison is possible.
