All three pilots were killed.
You can thank J. Richard Smith for that information, incidentally.
As for studies of the unit, there's a section in Jean-Bernard Frappé's "La Luftwaffe Face au Débarquement Allié" (Editions Heimdal, Chateau de Damigny, 1999) that deals with it and there is a bit in vol. 4 of Jochen Prien's "Geschichte des Jagdgeschwaders 77" but only for the week or so that II./JG 77 operated alongside them.
My website deals with the some of the
Gruppe's operations in August 1944 and has an article about its partial successor,
Sondersstaffel Kaatsch.
Both Prien and Frappé were under the misapprehension (from German sources, I'd guess) that one JG 200 pilot shot down in August was killed when in fact he survived and was taken prisoner.
