match SCs from the cluster in L2 to L1

Now we have to map the other 3 SC in the transition tower correctly Sample 2 region 0 we treat as layer 3

Sample 2 region 1 is 1.425-2.5. First 2 cells here map onto last 2 barrel layer 1 (hence rescaling pos_neg to +/- 1)

Third cell in Sample 2 region 1 maps onto Sample 1 region 0

After which the OW is normal for a little bit...

Then we get to the next weird region (1.8=2.0)

Followed by normal again (2.0-2.4)

And finally one odd one (2.4-2.5)
