STNTUPLE datasets are defined by four parameters:
1. dataset name: self-explanatory
2. book name: two people may accidentally come up with the same dataset name. To avoid name collision, a dataset has a book name, which for example, could be a person's name - think of two files with the same name but in different folders
3. fileset name : in case of a large dataset, one may want to run only on a subset of files from that dataset. Fileset defines such a list of files from the same dataset. Disk-resident files from the same fileset are required to reside in the same directory. Fileset name = "" means all filesets in a dataset
4. file name: to run on a single file, one would need to specify the file name. File name = "" means all files in a given fileset
Public Mu2e STNTUPLE's are currently kept on BLUEARC disks, use book="bluearc" to access them.
Use http-based catalogs (defined in .rootrc file):
Stntuple.Catalog http://mu2e.fnal.gov/public/hep/computing/Stntuple/cafdfc
