Displaying profile files in Author Pane blocks

Hello all:

I've created some Profile module fields and added/enabled Author Pane module. Next, I've position the Author Pane in one of the blocks. I'd like to know how I can add the Profile fields within the Author Pane module. There a author-pane-block.tpl.php file I'm looking at. I need to know what variables represent the Profile fields.

Thanks, Jun D!
