Notes. (a) JP identifier from Jones & Prosser (1996).
(b) Number of filter/exposure combinations yielding photometric period derivations for a given star.
(c) Gyro ages determined using Meibom et al. (2009) I-sequence colour function coefficients, viz a=0.770 $\pm $ 0.014, b=0.553 $\pm $ 0.052 and c=0.472 $\pm $ 0.027, and an age function exponent n=0.5344 $\pm $ 0.0015 (see Sect. 5.1).
(d) Assuming a mean gyrochronology age for M 34 of 193 Myr (the mean of the ages calculated in Col. 6 - see Sect. 5.1) and the Meibom et al. (2009) coefficients, with n=0.5344 $\pm $ 0.0015, we use intrinsic (B-V) colours and Eq. (1) to derive a fitted period for each M 34 I-sequence star.
(e) Each star's contribution to the period variance [(Measured Period - Fitted Period)2] is noted, where the total variance is 43.73 days2, with a mean of 1.68 days2.
