As I thought, the SiPMs and chimneys closest to the backplane are numbers 1 and 16, and those farthest from the backplane and closest to the door are numbers 15 and 30.

Then bundle I have been testing is number 401, not 402, since the fiber color codes match the ones for bundle 401 given in the [https://docs.google.com/spreadsheets/d/1r0ie8X5TxzoVdzD2mMp-dMf9cRbptE4xoxn2mvrBsro/edit?ts=5a5661a0#gid=1603396283 Summer 2017 Fiber Data Log].

The data log shows yellow as the strap color on the Bundle 401 sheet and pink as the strap color on the Bundle 402 sheet. The Information sheet had the wrong colors for bundles 401 and 402, so I changed them.
I continued polishing the sci-fi bundle. Today I pressed harder and reached my goal with the 400 grit paper, which is to get 0.014" from the final length. I came close to the 0.025" feeler gauge on one end of the bundle and 0.029" with the feeler gauges on the other side.
2/27: I ran four tests on bundle 401. Yesterday Dr. Jones said I should pick the best fibers from this bundle for comparison with future test results. I think I might pick the best three from the fibers set forward and the best three from the ones set back. Since the graphs of the test results give the same mean as the mean in the text logs, I will probably use the mean text log column to pick the best fibers.
However, I would like to know how the standard deviation should affect my choice and what the other columns in the text logs mean.
