DESCRIPTION: 
Inter-Laboratory Mass Spectrometer Calibration Programs 
using empirically derived equations as described in Ostermann (2000). 

FORTRAN program files mat_convert.f and mat_unmix.f, 
and C program file curry19.c. 

mat_convert.f: 
This program converts raw isotopic data from Version 5.2 of ISODAT of 
the Finnigan MAT252 at WHOI into enrichments with resepct to VPDB, 
for the A and B lines. This program also corrects for gas-mixing 
in the source. 

mat_unmix.f: 
This program converts raw isotopic data from the WHOI Finnigan MAT252 
into enrichments with resepct to WHOI Reference Gas and corrects for 
gas-mixing in the source. 

curry19.c: 
C program to take raw data from Finnigan MAT252 mass spec, reformats 
the exponential notation to a fixed format and outputs only specific 
columns of information. The following lines of data must be selected 
using the "format editor" in ISODAT:
2) Date / Time 
3) Spec. -No / Sample Ident /Sample size 
10) Process Information 
13) Ion-gauge 
33) Std. Deviation 
38) Sample [ion corr]
