+# ASCII CTD file support

+
+# By default, [LADCPproc] reads a standard seabird .cnv file. Alternatively,
+# the CTD data can be supplied in a plain ASCII file. To do so, the following
+# variables must be defined in the setup file (-s). Each variable defines 
+# the field (column) number of the corresponding data field. Fields are
+# numbered beginning with 1.
+
+# $CTD_ASCII_sampfreq		= 1;  ## in Hz
+
+# $CTD_ASCII_press_field 	= 1;
+# $CTD_ASCII_temp_field 	= 2;
+# $CTD_ASCII_salin_field	= 3;
+# $CTD_ASCII_lat_field 		= 4;
+# $CTD_ASCII_lon_field 		= 5;
+
+# The following variable is optional.
+
+# $CTD_ASCII_badval 		= 999;
