The temperature difference (ΔT) between Tegg and Tair was
calculated and filtered to produce the ΔTfiltered signal representing
the final thermal profile. The ΔTfiltered signal was further processed
using a 10-h average window approach to investigate differences
in temperature. The following parameters of an identified temperature drop in ΔTfiltered were quantified for the MD, LD and focal
eggs (Fig. 1):
