+LIFT 27 June 2022 meeting
+- only raw, no subband data
+- cosmic ray uses all antennas of one station, lightning ~ 6 antennas but all Dutch stations
+  . 6 dual pol antennas per station with long baselines
+  . 96 LBA --> 8 - 16 possible useful combinations of 6 antennas --> dependent on RCU allocation
+- cosmic ray is commensal, lightning is dedicated mode
+- cosmic ray 2 ms event, lightning 1 s events
+- individually controlled antenna buffers
+- transient detection based on power after 40 - 80 MHz BPF
+- read out via LCU (with local storage, later TCP to CEP) or directly to CEP (UDP)
+- 2 * 8 GB / (12 * 16b / 8b * 0.2 GHz) =  3.33 s seems enough storage
+  . 3.33 * 16b / 14b = 3.81 s
+  . header overhead 5 % --> 3.81 * 0.95 = 3.61 s
