Luftwaffe Fighter Sectors

Does anyone know, or know where I can find out, the sector numbers the Luftwaffe used to identify their airspace?

As part of my research of the 388th Bomb Group’s B-17 Skipper “an” the Kids I wish to find out which two fighters her gunners could have claimed on the Eighth’s famous raid on Brux, Czechoslovakia on May 12, 1944.

I have records of Luftwaffe fighter activity and their claims of Alllied a/c and some of their own losses for that day but the locations of the activities are only referenced by “Sektor”.

Any help, much appreciated as always
