 Under-the-hood Improvements
 ---------------------------

 Bug Fixes
 ---------
 
 - Fixed bug associated with finding more than one file with the same name (but
   presumably different extensions).
+- Fixed differential atmospheric refraction (DAR) correction bug. This bug affected
+  datacubes combined using CoAdd3D(). Previously, the DAR was being computed, applied,

 - Fixed a bug associated with an incorrect date for the transition to the Mark4
   detector for Keck/LRIS RED.
