Loop;			F     //  Allowed options: F for Frodo loop,  B for Bilbo loop,  G for Gandalf loop.
Participant ID;		NCAR  //  Allowed options: SIO, NCAR, UEA, CIO-RUG, UBERN, MPI-BGC, TU, NIES, CMAR, NIWA.
Revised data?; 		Y     //  Allowed options: Y, N.
Revision number; 	1     //  Must be >0 if revised data = Y.  Must be 0 if revised data = N.
Averaged data?;		Y     //  Allowed options: Y, N. Y = file gives data averaged from analyses made over several days. N = file gives data from single day's analysis.
O2 scale info; 		SIO O2 laboratory O2 scale    // not necessary to include any of these comment fields for *revised* data.
CO2 scale info; 	NOAA X2007 scale
Ar scale info;		      //  Empty, blank fields such as this are acceptable for comment fields.
Regulator info; 	Air Liquide, Model-14         // Comment fields can be as long as necessary, but *no* carriage returns.
Precision details; 	Range of means from 2 independent runs of 4 determinations each.
Calibration details; 	6 primaries run annually to calibrate 6 secondaries which are then used to calibrate GOLLUMs.
Damage noted;  		None  
Other comments; 	Scripps recalibrated our primary stds, so GOLLUMs revised // *Mandatory* comments here if revised data = Y, explaining revision.
O2 analysis date;	20091022   //  Format: YYYYMMDD, or NaN if none of the cylinders were analysed for this species.
CO2 analysis date;	20091022   //  Format: YYYYMMDD, or NaN if none of the cylinders were analysed for this species.
Ar analysis date;	20091022   //  Format: YYYYMMDD, or NaN if this species not analysed for *any* cylinders.
