CBED pattern of FeS2 taken with the [110] electron-beam incidence. In the 001 and [00\bar 1] discs, HOLZ lines are asymmetric with respect to extinction lines A2, indicating the existence of a 21 screw axis parallel to the c axis. In the [\bar 1 10] and [1\bar10] discs, HOLZ lines are symmetric with respect to extinction lines A2, indicating existence of a glide plane perpendicular to the c axis.
