The mapping as it stands right now can be best shown in this picture from Mike:

There are two runs of data shown at:

drupal.star.bnl.gov/STAR/system/files/EPD_ADC_vs_TAC_ALL18146018.pdf

Let's see if they make sense.
Looking at PP4TT1 -> 32B with new FEE:

This looks pretty good ... though I thought the gain was supposed to be higher?  This doesn't look so different from before.  (TT 3, 5, 7 look fairly similar) But moving on.

Looking at PP4TT9 -> 32C with new FEE and modified TAC

So this is really representative of what we should get.  We can really see the effects of the gain here!  But I think this looks ok.
