All energies in MeV
PSF are defined as in RIPL-3: PSF=Eg**(-2L-1) x Gamma width x level density
JL defines PSF x Eg**(2L+1) instead
 
  PSFType=0 --> SLO
  PSFType=1 --> EGLO, as defined in RIPL-3, but using always Tf in the formula
  PSFType=2 --> SMLO, as defined in RIPL-3
  PSFType=3 --> GLO  (like EGLO, but k1=k2=1)
  PSFType=4 --> MGLO (like EGLO, but k2=1)
  PSFType=5 --> KMF
  PSFType=6 --> GH
  PSFType=7 --> EGLO, but the k parameter is provided (MEGLO)
  PSFType=8 --> EGLO, but the "k1" and "k2" parameters are provided (MEGLO)
  PSFType=9 --> EGLO, but the k parameter and a constant temperature of the nucleus is provided (MEGLO)
  PSFType=10 --> EGLO, but the "k1" and "k2" parameters and a constant temperature of the nucleus are provided (MEGLO)
  PSFType=11 --> SMLO, as defined in Eur. Phys. J. A (2019) 55: 172
  PSFType=20 --> gaussian (to simulate small bumps or resonances)
  PSFType=21 --> expo -->  C*exp(-eta*Eg). It is defined with three entries: C eta dummy
  PSFType=40 --> pointwise function type 1 (only input file)
  PSFType=41 --> pointwise function type 2 (only input file)
 
Procedure to obtain the PSF, in order of hierarchy:
  - Get the data from inputfname
  - Get the data from PSF_param.dat file
  - Get the data from IAEA-2019 PSF values (if PSFflag==0)
  - Get the data from RIPL-3 experimental MLO values --> gdr-parameters&errors-exp-MLO.dat
  - Get the data from RIPL-3 Theorethical values --> gdr-parameters-theor.dat
  - Use RIPL-3 and RIPL-2 theoretical formulas
