[APBeta] Seeing/Transparency

[Paul Rodman]

Folks,

A user has requested that the Seeing/Transparency be per observation*  
rather than per session, his argument being that those values change  
over the period of an observing session. Does anyone else have strong  
feelings about this either way?

As I see it (sic):

a. Per session: less hassle, but not so fine grained. If the seeing  
(say) changed from bad to good over the period of the session, it  
might not be clear as to why an observation was or wasn't successful.

b. Per observation: more hassle (although the default would be to make  
the value the same as for the last observation in the session).  
Session could display range of seeing/transparency based on its  
included observations.

* per resource-combination within an observation might be pushing it.
