This function seems a repetition of https://github.com/gem/oq-engine/blob/master/openquake/hazardlib/gsim/campbell_bozorgnia_2003.py#L41 Another possibility would have been to import this function rather than repeating it

The attenuation model developed by Campbell_Bozorgnia (2003) is added to perform the calculations for all conditions (soil types, ...) and for both horizontal and vertical components.
The changes made are:
1- A gsim library of "campbell_bozorgnia_2003_world" is added to openquake\hazardlib\gsim
2- A test file of "campbell_bozorgnia_2003_world_test" is added to openquake\hazardlib\tests\gsim
3- The verification tables of "campbell_bozorgnia_2003_world" is added to openquake\hazardlib\tests\gsim\data\CB03_W.
4- The "openquake.hazardlib.gsim.rst" file is modified so that it includes "campbell_bozorgnia_2003_world".
