Table 1:

Values of the rotational velocities for Be and Oe stars for several average mass categories.
Mass category	A	B	C	D	E
$\langle{M/M_{\odot}}\rangle$	3.7	7.6	10.8	13.5	23.7
N	14	82	13	15	7
$\langle{V\sin i}\rangle$	277	297	335	336	420
$\langle V\sin i\rangle_{\rm corr}$	300	326	376	377	457
$\log [{\rm age}({\rm yr})]$	8.3	7.6	7.3	7.2	6.9
$\langle{V}\rangle_{\rm ZAMS}^{\rm old}$	400	437	513	514	-
$\langle{V}\rangle_{\rm ZAMS}^{\rm new}$	448	487	562	563	683
$\epsilon_{V_{\rm ZAMS}}$	35	27	23	23	44
$\langle{V}\rangle_{\rm ZAMS}^{\rm magnet}$	389	423	488	489	643

Notes. N = number of stars by mass category; $\langle{V}\rangle_{\rm ZAMS}^{\rm old}$ = average true rotational velocities in km s^-1 without correction for GD (Martayan et al. 2007); $\langle{V}\rangle_{\rm ZAMS}^{\rm new}$ = average true rotational velocities in km s^-1 of the enlarged stellar sample, corrected for GD effect $\epsilon_{V_{\rm ZAMS}}$ = error of $\langle{V}\rangle_{\rm ZAMS}^{\rm new}$ in km s^-1; $\langle{V}\rangle_{\rm ZAMS}^{\rm magnet}$ = average true rotational velocities in km s^-1 of the enlarged stellar sample, corrected for models including magnetic fields.
