 == What is MINIMUM_ZETA? ==
 MINIMUM_ZETA is a parameter determining how close reflections may be to the 'blind region' of reciprocal space to still be integrated. On the detector, the blind region consists of two cones starting at the direct beam position, and extending along the spindle, to both directions.
-A high value (corresponding to a large blind region) is "safe" but produces lower completeness because more pixels of the detector are considered to be in the blind region. The default of 0.15 is on the safe side. I (Kay Diederichs) routinely use 0.05 now.
-Update March 2012: the default was changed to 0.05 (Version December 31, 2011) after changing the integration algorithm to deal better with reflections near the rotation axis - see [http://homes.mpimf-heidelberg.mpg.de/~kabsch/xds/html_doc/Release_Notes.html].
 == How could I check if a low value of MINIMUM_ZETA is beneficial for my data reduction? ==
