Steve:
Yes, these bits formerly used for adjacent jet patch use are now gone, so we do not have output bits that handle JP bits for individual jet patches.

>Also bits 0-7 used to carry Etot - now are gone, right?

Etot out of each layer 1 DSM is now reduced to 5 bits, 0-4, in order to allow Eleanor to form the sum of 8 layer 1 DSM's in the layer 2 DSM.  Bits 5-6 are now empty, and bit 7 has been reassigned to register-selected HT x TP threshold.
