Post-Processing Programs
Post-Processing requires a number of steps:
- ASCII data is downloaded from Isodat 5.3 with a format which includes the
following Isodat format line numbers:
| 2 | Date/Time |
| 3 |
Spec. -No / Sample Ident / Sample Size |
| 10 | Process information |
| 13 | Ion-gauge |
| 33 | Std. Deviation |
| 38 | sample [ion corr.] |
- We run a C program called
curry19.c which reformats the data
- We run a fortran program
mat253.unmix.f to
correct raw and formatted data for
gas mixing in the source. Mean NBS19 values are calculated for the A
and B lines
and a conversion to VPDB value is calculated and then entered
in mat253.convert.f.
- The last step is to run a fortran program called
mat253.convert.f
includes mat253.unmix.f plus the specific
A or B line conversion values to VPDB.
