Example 3: iGRC tableΒΆ
This example reproduces the nominal iGRC table in Annex F [1]. It also allows for seeing the table with different impact angles, for ballistic descent, as well as with and without both obstacles and the conservative assumption of -0.3 (see details in Annex F).
First, we call the AnnexFTables class (the called method is static).
console_output = AnnexFTables.iGRC_tables(show_with_obstacles = True,
show_ballistic = False,
show_with_conservative_compensation = False,
show_glide_angle = False,
show_additional_pop_density = True)
The returned value is a list of strings to print to the console, which we then do.
for s in console_output:
print(s)
