Notes.
Parameters of UVWEIGHT command in DIFMAP. The first number gives the size of the grid used in determining weights in the uniform weighting scheme; “5” = 5 × 5. “2” = 2 × 2, and “0” means natural weighting. The second number gives the exponent of the weighting based on the visibility errors, i.e, data are weighted either by σ−1 or σ−2.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
