How do I know which CCF were used to reduce my
event list?
All event lists produced by the PPS
(or the SAS
procs) contain a
CALINDEX
extension. This extension lists the CCF files that were used to process the
data. You can use this extension of the
event list as your Calibration Index File (CIF),
just pointing the environmental
variable
SAS_CCF to the event list file name.
The variable
SAS_CCFPATH needs to be set to
the directory where the CCF files are physically located.
With these settings, the SAS will try and use
the CCF files listed in the
CALINDEX extension. If they are not
available on your disk an error will be generated.
Because any dataset with a CALINDEX extension can be used as a CIF,
commands like
cifdiff can be applied.
