My apologies to both you and grandparent, I faux-pass'd on using such sloppy jargon in a thread of general interest. If I can be useful in decoding some of that and helping to keep this topic accessible to the broader community I'd be happy to answer any questions about what I meant. I've cited a few useful resources elsewhere in the thread and am always eager to talk shop on topics like this, so fire away if you have any questions about the field or what the hell I was talking about :)
