positive.code: Near surface XBT data,Remove rejected levels,CSIRO_depth,Standard reject of XBT data < 3.6 m
  Wire break,Remove below reject,CSIRO_wire_break,Expert opinion is that this is highly reliable at detecting XBT wire breaks
  Depth above surface,Remove rejected levels,ICDC_aqc_01_level_order,Flags depths less than zero (plus preprocessing for other ICDC checks)
