particle data macros

Hi
Can someone help me locate macros for particle data which are not specified in the udf manual in the Ansys src folder?

I am looking for particle reynolds number and drag coeff and some other values I am sure Fluent calculates, for example Re is passed in the DEFINE_DPM_DRAG macro but I cant locate the macro for the particle reynolds number in the fluent src folder.

For the macros in Table 3.26: in the user manual it says "Macros for Particles at Current Position Defined in dpm.h". But I cant even find them in dpm.h, are they really in there or not?
Thanks

Just to let others know too

macro for re number is

RE_NUMBER(density,velocity,diameter,viscosity).

Not sure where this can be found in the src folder.

Also, if someone does come across the particle macros in dpm.h or somewhere else please post here, I cant find them.

Edited " More are in dpm_types.h, still not a full list though".
Cheers
