5-31-22: 5-trial averages

Overall, pixels of high SNR do not appear in groups. Occasionally in groups of 2-3 px.

Possibly an issue with pixel arrangement in TSM-to-ZDA load? Decrease measure window to width of 1, and show Max Amp, it should look like RLI frame? But with other sample ZDA taken from old rig, this isn't the case either.

Fixed issue. Seems now unambiguously good result? Previous analysis to be repeated.

Mid-stim SNRs, at 200 uA, of 2.45, 2.67, 2.61, compare to old rig of 1.43, 1.27, 1.33, 1.34, 1.44 (from 2/9/22 01_01_01, 01_01_02 and 5/12/22 01_01_01, 01_01_02, 02_01_01):

The SNR_new / SNR_old ratio for these slices is thus 2.58 / 1.36 = 1.89
