    notes
    BD-1: one mag 0 flash, timings 23.19 and 28.41
    BD-2: Likely a complex period consisting of following groups:
          (1.66 2.26 2.63 2.30 1.77 3.29 3.55 3.75) = 21.21 and
          (1.34 2.51 2.65 2.32 1.76 3.33 3.20 4.06) = 21.17
    BD-3: No repetition of pattern found: assumption of 1 period:
          (29.21 9.10 104.30)
    BD-4: Probably part of one period.
    BD-5: timings: (9.96 10.62) 21.90 (10.26 11.38) 19.10 23.07
          20.66 21.67 20.68 (10.78 10.80)
    BD-6: timings: 48.76(2) 25.64 71.66 (3) 23.86 (mag -1 flash)
          25.74 49.96 (2) 28.46 23.54
    BD-7: asymmetrical intervals; combined period reported:
          timings: (8.68 9.09) (8.77 9.06) (8.95 9.15) (8.76 9.38)
          (8.83 8.92) (8.46 9.48) (9.03 8.91) (8.96 9.00) (8.92 9.28)
          (8.56 9.36) (8.72 9.25)
    BD-8: Irregular; following combined periods are a guess:
          timings: (3.54 4.00 17.93 1.54) (1.49 8.57 8.75 11.01)
          (7.66 5.22 8.60 5.64)
