Figure F12. Magnetic moment for the x-, y-, and z-axes measured for an empty discrete sample tray sitting within the sample boat. The moment was measured along the 150-cm-long tray. A. Prior to cleaning. B. After the tray was cleaned with window cleaner and AF demagnetized at 60 mT. C. Several days later after the tray was cleaned and empty plastic cubes were inserted in the discrete sample holder positions
