BTO values in the communication log
From the communication log, I get the following BTO values
TimeBTO=[0 12 13 25 37 118 191 251 311 371 461]; % min from 16:30
BTO =[14920 14940 14920 15200 15600 12500 11500 11740 12780 14540 18040]; % µs
and applying the BTO formula (1) page 54 of the ATSB report, I get the following ping ring radiuses:
PingRad =[2243 2241 2238 2267 2309 1904 1758 1798 1953 2194 2621]; % NM
and the following elevation angles:
ElevAng =[46.72 46.76 46.81 46.27 45.48 53.10 55.87 55.12 52.17 47.63 39.70]; % degrees
(I have also generated kml files for these ping rings to compare visually with those of the figure 18 of the ASTB report)
Do you get similar values ? (radiuses and elev. angles). They seems to differ from Duncan Steel's.
