Possibilities for spatial reference info in a tif

I am trying to get a list together of the many ways that ArcGIS can read spatial reference info from a tif file.  There can be info in header information, there can be a tfw, or esri auxiliary files, etc.  Can anyone elaborate on those methods and add a few more?  Also, what is ArcGIS order priority on which method it uses?  My concern is when tifs are moved between software and there could be different spatial reference information listed in different places.  It would be nice to know how to look for spatial reference in each method to compare and confirm that they are the same.
