Analysis of subsets of data. Image numbers are given as ranges under bars, and each frame represents 0.1°. (a) Twin fractions versus rotation range in three data sets [called Ainv, Achi10 and A (reindexed)]. Refinement of the final model against subsets of frames from each data set showed a smoothly varying twin fraction. Colored bars represent wedges from different data sets as indicated. (b) Efficacy of MR by two measures: Phaser Max LLG (blue) and (1 − normalized CPU time) (red). The latter unconventional inverse measure was used to show the relationship more clearly. (c) Anomalous signal is shown as the average peak height of the 16 highest-magnitude anomalous peaks (blue), further averaged across the three data sweeps and with values above bars in sigmas. Note that in better data sets these peaks correspond to the 16 known calcium sites, whereas in worse cases these averages include some negative (false) peaks of large magnitude. Red bars indicate twin fractions.
