- Makefiles included here are those required for micromegas to use looptools (change the LoopTools directory to match your install)
- improveCS.c is included here, which allows micromegas to calculate relic *annihilation cross sections to be calculated with varying temperature
- ensure that you set the correct flag for the loop level ffh vertex - the loop needs to be evaluated at the correct scale
- include looptools.h in your main.c and call ltini() before your code and ltexi() after

When using model, set appropriate flag for your calculation to 1 and others to 0:
 - RelFlag - for computing relic density
 - DDFLag - for computing DM direct detection
 - HinvFlag - for computing H->psi psi decays

Correct calculation of relic abundance should use lib/improveCS.c (put in micromegas project/lib directory),
this will allow temperature dependent calculation of the loop)
