<p>Following discussion in&nbsp;</p> <p>&nbsp;</p> <p>https://github.com/HDRMX/NXmx/wiki/Treatment-of-(Dynamic)-Shadows-in-Eiger-Data-Sets</p> <p>&nbsp;</p> <p>example Eiger data set with shadow mask added under /entry/shadow/dynamic_mask - uploading for discussion purposes only, data set may be revised in future. Clearly any and all are welcome to look at / inspect the files and provide commentary.&nbsp;</p> <p>&nbsp;</p> <p>N.B. the shadow model has not been optimised.&nbsp;</p>
