########### List of extension tabel of the experiment ER012C #############
CL1 = CL table created when loading data (CL int =2 secs)
SN1 = Output of running ANCAL on TY and GC tables
CL2 = The apriori amplitdue calibration (CL1 * SN1)
FG1 = Flagging band edges
SN2 = The phase, delay and phase rate solutions derived from sources
        identified as calibrators via FRING
      Calibrators: J1157+1638  J0657 1613+341
      (Mapping failed for DA193 - due to weighting - so it was removed
       from pipeline)
      Flags in FG1
      SOLINT= 2.5 min
CL3 = CL2 * SN2 (the application of SN2 to CL2)
BP1 = Bandpass amplitude *NOT* phase (the application of CL2 and FG1)
SN3 = Amplitude and phase gain corrections derived from crude maps of 
      calibrator J1157+1638
SN4 = Amplitude and phase gain corrections derived from crude maps of 
      calibrator J0657
SN5 = Amplitude and phase gain corrections derived from crude maps of 
      calibrator 1613+341
CL4 = CL3 * (SN3+SN4+SN5) i.e. the application of SN3 through SN5 to CL3)
