 *) #1860: Use beamlet clipping for correlator and TAB
-  - dish beamlet output -->
-    . clip instead of wrap is better for Apertif X, see email 17 apr 2017 (Work in progress) and correlator_null_clip_or_wrap.m
-    . for SR3,4 IAB using clip is preferred, similar as for X
-    . for voltage TAB (even after F_chan) using wrap can cancel from some amount of overflow due to RFI
-    . advantage of using clip is that it also kind of flags the data, whereas wrap kind of scrambles the data
-    . advantage of only using clip is that we do not have to select between clip and wrap per Apertif X and Arts SC
-    --> Conclusion: Use clip in node_apertif_unb1_fn_beamformer
-    . however if clipping occurs then there is RFI, so the visibility will not be useful anyway
-    --> Conclusion: Keep wrap in node_apertif_unb1_fn_beamformer
