#NAMELISTS
Passes parameters to multimodecode_driver.f90 without the need for recompiling.

----------------
Parameters to control the major functionality of ModeCode
Set potential and its derivatives in modpk_potential.f90

&init
  num_inflaton = 10
  potential_choice = 1
  vparam_rows = 4
  slowroll_infl_end = .true.
  instreheat = .false.
/

----------------
Parameters to control the output of analytic approximations for
comparison.  The deltaN calculation is only valid for
sum-separable potentials.  The horizon crossing approximation (HCA)
ignores the contributions from the end of inflation surface.

&analytical
  use_deltaN_SR = .true.
  use_horiz_cross_approx = .false.
  evaluate_modes = .true.
  get_runningofrunning = .true.
/


----------------
Parameters to control how the ICs are sampled

ic_sampling = {1=reg_samp, 2=eqen_samp, 3=slowroll_samp,
  6=isoN}

&ic_sampling_nml
  ic_sampling = 1
  numb_samples = 1

  energy_scale = .1

  save_iso_N = .false.
  N_iso_ref = 55

/

----------------
Parameters to control how the vparams are sampled.
The vparams get marginalized --- detailed output is not saved.
IMPORTANT: If param_sampling/=reg_constant, then this overrides the specific choices of
vparams in namelist &params.

param_sampling are {1=reg_constant, 2=unif_prior, 3=log_prior}
  NB: Not all combinations of param_sampling and ic_sampling work together.

&param_sampling_nml
  param_sampling = 1

  use_first_priorval = .true.

  vp_prior_min(1,:) = -14

  vp_prior_max(1,:) = -12

  varying_N_pivot = .false.

/

----------------
Parameters to be passed to the potential
NB: If ic_sampling=parameter_loop_samp, then the smallest vparams equals
the smallest mass; others are discarded.

&params
  N_pivot = 55.0
  k_pivot = 0.002
  dlnk = 0.4

  phi_init0 = 10.0 10.0 10.0 10.0 10.0 10.0 10.0 10.0 10.0 10.0

/

----------------
Priors on the IC and N_pivot ranges
Uniform priors on fields and dphi/dt (NOT dphi/DN)

For calculating the full power spectrum P(k).  Samples in
uniform increments in log(k).

&full_pk
  calc_full_pk = .false.
  steps = 300

----------------
Options for output from the code.

  out_opt%modes = .true.

/

----------------
Advanced options for technical features.
Use DVODE integrator for stiff problems.
Set accuracy_setting = {0,1,2} for increasingly accurate integration.
Use accuracy_setting = {-1} for manual settings that depend on choice of integrator.
DVODE uses both a relative and absolute tolerance.
Set rtol to 10^-(m+1) where m = # decimal places that are important.
Set atol_i where |y_i| is insignificant.
