+# AntennaSet.conf

+# This file defines subsets of the (physical) antennafields that can be used
+# in observations as 'the' antennafield.
+#
+# Since there are 3 different station layout each subset must be defined for
+# each stationtype (Core, Remote and Europe).
+#
+# A Subset is defined for specifying for each stationtypes for each RCU which
+# input is used.
+#
+# Allowed values for the RCU input selection are:
+#	H : HBA input
+#	h : LBH input
+#	l : LBL input
+#	. : RCU not included
+#
+# To diminish the typing-work to syntax of an rcu definition is:
+#   input-selector ::=  H | h | l | .
+#	rcu_definition ::= number input-selector [ number inputselector ...]
+#
+# E.g. when on a station on all RCUs the HBA input must be used this can be defined as
+#      192H  in stead of 192 'H' after each other.
+#
+# Or when all even RCUs should use LBL and all even RCUs shoud use LBH:
+#	   96hl
