Dat entry for sinking corpses

Age of Empires II: DE II - Modding
1

Anyone know the entry in the empires2_x2_p1.dat file for the duration in which dead bodies sink into the ground?
Like in this mod https://www.ageofempires.com/mods/details/1138/
I just can’t find the correct entry.
Thanks for any help

Description from Persistent Corpses mod should help.
