3600s BG scan running on the one in the chamber- using it's current fine tuned peak value of 4.8us.
Over this winter I'll redo all the element scans from my article on APXS/XRF with the Si-PIN detector and CdTe detector. That will be the final chapter until some iridium shows up- what was thought to be Ir in the original NaI(Tl) scans were later confirmed with the SDD to actually be W.
Grrrrrrrrr..........That was my SECOND mistake!
