Tutorial 10

Step	Input	Processor	Output
GetRaw	MBS	default	none
Unpack1	Input of GetRaw	MakeUnp1	EventUnp1
Cal1	EventUnp1	MakeCal1	EventCal1
RestCal1	EventCal1	default	none
Unpack2	Input of GetRaw	MakeUnp2	EventUnp2
Cal2	EventUnp2	MakeCal2	EventCal2
RestCal2	EventCal2	default	none
Physics	Input of RestCal1 and RestCal2	MakePhys	EventPhys

We now want to exercise to store data and retrieve it in different phases.
The file names are specified in setup.C and can be changed in the configuration menu.
For convenience we provide another macro to configure the following settings.
Download control.C and execute it in TSt8Analysis behind setup.C.

1. Store unpacked data

   Step	Source	Process	Store
   GetRaw	on	on	off
   Unpack1	off	on	on
   Cal1	off	off	off
   RestCal1	off	off	off
   Unpack2	off	on	on
   Cal2	off	off	off
   RestCal2	off	off	off
   Physics	off	off	off

   The unpack sources are off.
   They get their input from MBS input which must be enabled.
   Store their output events into files. All others are not used yet.

2. Read unpacked data, store calibrated data

   Step	Source	Process	Store
   GetRaw	off	off	off
   Unpack1	off	off	off
   Cal1	on	on	on
   RestCal1	off	off	off
   Unpack2	off	off	off
   Cal2	on	on	on
   RestCal2	off	off	off
   Physics	off	off	off

   Now the MBS and the unpack steps are no longer needed.
   The calibration steps get their inputs from the files written before
   and store their events in other files.

3. Read calibrated data, store physics data

   Step	Source	Process	Store
   GetRaw	off	off	off
   Unpack1	off	off	off
   Cal1	off	off	off
   RestCal1	on	on	off
   Unpack2	off	off	off
   Cal2	off	off	off
   RestCal2	on	on	off
   Physics	off	on	on

   Now we need the two RestCal steps to read the data
   written by the calibration steps before from files.
   Physics has source off because it gets its input from the two RestCal steps.
   The results are stored in final file.

We recommend to configure these phases and store them as described at the end of Tutorial 7.
