1. ============  Spectrum Calculation ======================
For computing the spectrum we rely on NMSSMTools.
Two options are available,  SUGRA and LowScaleInput depending whether input
parameters are defined at the GUT scale or at the EWSB scale.
To choose one option, please uncomment one of the  instructions  
// #define EWSB
// #define SUGRA
at the top of the main.c file.

For example, for the SUGRA option call
   ./main 1000 130 -1500 10 0.1 -50 1 171.4
and for  LowScaleInput
   ./main data1.par

In both cases if you launch 'main' without parameters, the parameters needed are
specified on the screen. 

2. If both #define instructions are commented then micrOMEGAs expects that a SLHA file
containing the calculated spectrum is passed in command line, for example 
   ./main spectr
micrOMEGAs  works  only  with SLHA spectrum files obtained by NMSSMTools
because they contain the effective couplings in the Higgs potential.  
 
3. New parameters are added in the NMSSM Lagrangian. In terms of Eq.(2.1) and
(2.5) of [1]  they are
 mXiS= $\xi_S/\sqrt{|\xi_S|}$
 muP = $\mu^'$
 m3h = $m_3^2/\sqrt{|m_3^2|}$
 msP = $m_S^{'2}/\sqrt{|m_S^{'2}|}$
 mXiF= $\xi_F^\frac{1}{3}$

All these parameters are given in GeV units.

The file  data_notZ3.par contains a set of electroweak scale  input parameters with non zero
mXiS and mXiF. It corresponds to ../Packages/NMSSMToosl_4.4.1/SAMPLES/inp.par

4. The SUGRA scenario is realized by a call to the function
    nmssmSUGRA($M_0$,$M_\frac{1}{2}$ ,$A_0$ ,$tb(MZ)$, $sgn(\mu)$,
               $\lambda(SUSY)$, $A_\lambda$, $A_\kappa$,
               mXiF, mXiS, muP, msP,m3h)

where all parameters except tb and \lambda are defined at the GUT scale. 
When calling the main program with the SUGRA option, main.c 
uses zero values for the last 5 parameters. To use other values the user has to define 
them explicitly in main.c[F].
