722	IMPORTANT: Correction for the output observation NetCDF for DART	arango	arango	"There were couple of issues with the output observations NetCDF file ('''MODNAME''') used in '''4D-Var''' and '''DART''' (Kalman filter) to report the model values at the observation locations and other important '''4D-Var''' variables.  We need to correct the '''survey''' dimension since it was one value too many. And correct the number observations with the same survey time ('''Nobs''').  This variable has the wrong dimension ('''state_var''') with the wrong values.  It was confused with new variable '''Nused_obs''' containing the number of usable (viable) observation per each state variable.

Many thanks to Andy Moore for bringing this to my attention."	bug	closed	major	Release ROMS/TOMS 3.7	Nonlinear	3.7	Fixed
