Monitoring

• Monitoring jobs will be run on new data as it is written to tape. These jobs will do several things:

• If calibration / reconstruction-improvement work is ongoing, monitoring jobs will also be rerun on tape data at regular intervals. This may be weekly or bi-weekly, and may run over all of the data for the given run period, or only a subset of it, as the situation demands.

Reconstruction

REST-format reconstruction data will be saved to tape at JLab. If the disk footprint is small enough, all of the REST reconstruction results will be stored on the /halld/volatile/ disk. If not, then a 2-track skim of the data will be available.

Physical Skimming

• Physical, EVIO-format skims will be made available to the calibration on the /halld/volatile/ disk as needed to assist with calibration studies. No other physical skims will be created.

Logical Skimming

• Logical skims will be stored in EventStore. These will be created by running the
