 # Author: Eric Kooistra
 # Purpose: Start WG synchronously at multiple dishes
 # Usage:
-# . First use util_bsn_source.py on a dish to read the current BSN
+# 
+# At ccu-corr.
+#
+# Edit this script to set the desired WG amplitude and frequency via subband, channel

+#   ssh lcu-rtc -X "python $UPE/peripherals/util_bsn_source.py --unb 0 --bn 0 -n 7"
+#
+# The BSN increments by 800000 every 1.024 sec, so e.g. start WG 30 sync periods of 1.024s from now:
 #
-#   ccu-corr> ssh lcu-rtc -X "python $UPE/peripherals/util_bsn_source.py --unb 0 --bn 0 -n 7"   # read current BSN @ sync
+#   Calcuclate <start BSN> = <current BSN> + 30 * 800000

-# . The BSN increments by 800000 every 1.024 sec, so e.g. start WG about 30 sec from now:
