 # 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
 # 
-#   ccu-corr> ssh lcu-rtc -X "python $UPE/peripherals/util_bsn_source.py --unb 0 --bn 0 -n 7"   # read current BSN @ sync
+# At ccu-corr.
 #
-# . The BSN increments by 800000 every 1.024 sec, so e.g. start WG about 30 sec from now:
-#     start BSN = current BSN + 30 * 800000
-# . Then start the WG at all dishes using:
+# Edit this script to set the desired WG amplitude and frequency via subband, channel
 #
-#   ccu-corr> python tests/run_command_on_lcus.py --tel 2,3 -s 'start_wg_at_bsn.sh <start BSN>'
+# First use util_bsn_source.py on a dish to read the <current BSN> at sync

+# The BSN increments by 800000 every 1.024 sec, so e.g. start WG 30 sync periods of 1.024s from now:
+#
+#   Calcuclate <start BSN> = <current BSN> + 30 * 800000

+# To start the WG on a single dish use:
