Chris,

On the concept that there are no rules in tass, you can do what you want 
about posting, considering that some people have to pay to receive long posts.

My preference is to send them to Michael Richmond as a short technical 
note.  Then those that want to see them can.  There are no rules for tech 
notes - other than they have to have a name and number, so it is quite 
appropriate to put a couple of figures in a tech note.

Note that this is what tech notes are for.  You have made a couple of 
measurements and come to some conclusion.  Just right for a tech note.
