Imaging DetailsK2 SUMMIT DIRECT DETECTOR DEVICE OPERATED IN SUPER RESOLUTION MODE WITH A 1.64 ANGSTROM PHYSICAL PIXEL AND 0. 82 ANGSTROM SUPER RESOLUTION PIXEL. WITH NO SPECIMEN PRESENT, THE RATE OF EXPOSURE OF THE DETECTOR WAS 8 ELECTRONS PER PIXEL PER SECOND. EXPOSURE FRACTIONATED MOVIES OF 20.1 S WERE RECORDED AS STACKS OF 67 FRAMES, SO THAT SELECTED SPECIMEN AREAS WERE EXPOSED WITH A TOTAL OF 60.3 ELECTRONS PER SQUARE ANGSTROM.
