     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint59f
 o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode) 
 o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in 
   a bounded range (in forward mode)
 o pkg/ecco, ctrl, autodiff and mom_common:
  internal parameter controls, completements of implementations
 o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
+o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
+  (not seem any difference in testing results).
 o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains 
    at face corners.
 o pkg/generic_advdiff:
