BFEM ROOT Files
If you have been paying attention..you may have noticed that there are seemingly endless versions of the GLAST BFEM Root files. There are number of reasons for this:
The GLAST ROOT class structure was in flux.
Bug / omissions were discovered in ROOTWriter and/or bfemApp
When in doubt - use the most recent version of the ROOT files. Ultimately, there will be one last re-processing of all BFEM data files that will represent the final version.
All data files are located in:
/nfs/farm/g/glast/u05/bfem/data/
And available via FTP from:
ftp-glast.slac.stanford.edu/glast.05/bfem/data/
There are 2 underlying directories: flight and test
Where flight contains data files from the actual filght, and test contains data
files created during the testing at SLAC, GSFC, and NSBF (the balloon facility).
There is a naming convention to the GLAST BFEM ROOT data
directories, something like:
RWvnrm_DIGIvirj
Where, RWvnrm, refers to the tagged version of
ROOTWriter used to generate the raw data files and DIGIvirj
is the tagged version of the digiRootData package.
