gainmatrix3 - 2017 gains to start, master sim-recon branch
Layers2 - workfest sim-recon, June 6, 2018 ccdb constants
Layers5 - the same, but including layer 4 events
Exclusive1 - starts from the end of Layers5, C-matrix inversion method, massbias/10, E1, E2 > 0.5 GeV
Exclusive2 - the same, but massbias/20
Exclusive3 - starts from June 6 ccdb constants, still workfest sim-recon, massbias/10
Layers6 - sim-recon ver. 2.37, July 19, 2018 ccdb constants, including layer 4 events
Exclusive4 - sim-recon ver. 2.37, July 19, 2018 ccdb constants, C-matrix inversion method, massbias/10, E1, E2 > 0.5 GeV

~~~ Data set resolution test ~~~
gainmatrix4 - sim-recon ver. 2.37, July 19, 2018 ccdb constants for first iteration, Aug. 1, 2018 ccdb constants for all else, non-layers-skim test
   - Edited gainmatrix4Iter9.txt to try to get high fit channels (789 and 791) to converge to pi0 mass more quickly
   - Edited gainmatrix4Iter11.txt (channel 789) - multiplied by 0.9
Layers7 - same as gainmatrix4, but using layers skim (equal parts layers 1, 2, and 3 plus layer 4)
Layers8 - same as Layers7, but using all layers skim files

~~~ CCDB resolution test ~~~
Layers9 - sim-recon ver. 2.37, Aug. 1, 2018 ccdb constants
Layers10 - sim-recon ver. 2.37, May 2, 2018 ccdb constants
Layers11 - sim-recon ver. 2.37, July 19, 2018 ccdb constants

gainmatrix5 - sim-recon ver. 2.37, Aug. 1, 2018 ccdb constants, starting from Layers2Iter12.txt
Cosmics - sim-recon ver. 2.37, Aug. 20, 2018 ccdb constants (end of gainmatrix4) PLUS Layer 4 corrections from Colleen's cosmic calibration
