-# HISTORY:
-#	Aug 30, 2006: - created at end of GRAVILUCK cruise
-#	Aug 31, 2006: - BUG: ensembles/bins were numbered from 0
-#				  - added -d)imensional coords
-#	Sep  1, 2006: - fiddled with registration
-#	Sep 19, 2007: - adapted to new [RDI_BB_Read.pl]
-#	Jun 18, 2009: - BUG: xysize had been called xyside
-#   Mar 17, 2016: - adapted to new Getopt library
-#	May 19, 2016: - adapted to velBeamToEarth()
-
-# NOTES:
-#	- regular grids only => no dimensional time axis for data collected
-#	  in multi-ensemble burst mode!
-
-# TODO:
-#	- implement soundspeed corretion
-#	- add temporal pre-averaging
