[Loops] loops and thermal nonequilibrium

[Leon Golub]

Jim,

Amy and I addressed the issues of excess density, flat temperature 
profiles and large scale height about 10 years ago. Having flows of 
30-40 km/sec, as is observed in TRACE and now verified by EIS, solves 
these problems quite nicely. So there is a viable mechanism other than 
nanoflares.
