sharepoint [user information list] column names

I am able to query the [User Information List] via code in Visual Studio but I cannot find the actual column names for the table. I can also work with this table via Access 2007 Linked to SharePoint. It uses friendly names as opposed to the actual names like "ows_name" etc. Is there a list somewhere that has the actual default column names? I can access this list via code or Access 2007 linked tables but for some reason CAML query builder and Stramit.CamlViewer2007 give me access denied. I also get the same message if I go to http://thewebsite/_catalogs/users/simple.aspx .

So I am unable to see the column names. In code I am not having luck guessing the names. Of course it woudl have been great for Microsoft to just have a field that is the name called name but that would be to easy :)
