+# NOTES:
+#	- THE CORE OF THIS CODE IS A SIMPLE TRANSCRIPTION OF MERGE.C WRITTEN BY ERIC FIRING
+#	- comments starting with ## are taken from Eric's code
+#	- CTD elapsed time is estimated from recno * CTD_sampint
+#	- CTD_elapsed is undefined for records before instrument is in the water
+#	- ITS-90 temp field in degC required
+#	- salin field prequired
+#	- pressure field in dbar required
+
+# HISTORY:
+#	Sep 16, 2010: - incepted
+#	Oct 13, 2010: - first working version
+#	Oct 14, 2010: - renamed from LADCPshear
+#	Oct 19, 2010: - added -a)coustic backscatter profiles
+#	Oct 20, 2010: - added -2)dary CTD sensors
+#	Oct 23, 2010: - added magnetic-declination correction
+#	Oct 26, 2010: - added tilt calculation
