2023-11-07: Menlo counter data collection 1 S/s started, new figures
2023-04-12: Migrated comb-plots to new computer. Data before migration.
2023-02-18: residual cavity drift as seen by ion, average of C1,2,4 line-center drifts, computed continuously three times per servocycle
2022-10-19: add txt-file with predicted zeeman aom line-center
