[Halld-offline] [EXTERNAL] G3/4 comparisons for KSigma t-channel

I'd like to clear up some confusion from the production & analysis meeting
yesterday, as it's relevant to the G4 group.

We were talking about the dip in KSigma u-channel data seen in G4 but not
G3.
Richard asked about the t-channel.

There are comparisons of G3 & G4 for the t-channel in Nilanga's analysis
report, on the page before the u-channel.  I'll paste in screenshots of
both pages below.
They're on pp 83&84 of this:

However I have only seen comparisons with the data for G3 (for both t and u
channels).
Those are shown on page 11 of this:

Best,
Naomi.
