Thesis
 
My thesis can be found in the online library of the RijksUniversiteit Groningen.
 
Thesis “The Opacity of Spiral Galaxy Disks”
 
Most of the above papers are in this these as well as much extra material. If you would like a paper copy, email me.
 
The data of the WFPC2 fields is now publically available through the High-Level Science Products
of the MAST archive here as well as through NED.
Should you use this data I would appreciate a reference to my papers. But please do!
