Discussion
- Body temperature is guessed
- males are assumed to differ from females by {p_Am} only
- mod_1: v is reduced, weight data revised
- mod_2: Pseudo-data point k is used, rather than k_J; Data set tp and parameter t_R are added, the latter replacing clutch interval t_N. Postnatal T is based on PrinPres1991, see get_T_Aves. See further the revision page, theme puberty
