Zoom test-data: explanations & read-out

[astellhorn]

The example polarization data from ZOOM (attached) (long 3He runs for data reduction with glassy carbon as non-magnetic sample (GC) for reference):
1) I^(DB, unpol-in, cell):
#691 693 695 697
2) I^(++, +-, -+, --):
#690 692 694 696
--> dont have these, ask Diego again (but sample data from users, so maybe not accessible)
--> maybe can use GC measurements in folder "3He_GC" for sample-measurements?
3) I^(DB, unpol-in, cell)_background:
#698
--> for background subtraction
--> they have made an extra measurement, whereas we chose to just take the bg and some edge of the detector at certain Q
4) I^(DB, depol, cell):
#699
5) I^(DB, no-cell)
--> missing compared to our workflow!
--> just for normalization, maybe possible to set to 1?
6) Probably related to the "unpolarized SANS" workflow:
#706
--> "TRANS Reference of DB with GC"
--> sample transmission correction

Note: each ZOOM-file contains all 4 spin-values that we need to extract out to match to our workflow, see note above
