In any particular table row, the upper entry is earlier, the lower entry is later.
Results of #1, #2 and #5 suggest that some percentage of the RTXT part could be good enough for IceCube.
Short term stability appears to improves (toward an asymptote) as
parts accumulate more time under power..
For these samples, the integrated operating time was not recorded, unfortunately...
Statistics are poor.
Note that #4 didn't improve to the level of acceptability.
Note that #2 doesn't appear to settle down.
When time permits, both #2 and #4 will be burned in longer and retested.
