RECENT EFIT CHANGES

1. New EFIT E-coil Connections

2. Optional fitting of E-coil currents

IECURR
switch, 2 to turn on fitting. Defaulted to 1 treated as given.
FWTEC
fitting weights for E-coils. Array of 6 elements.
BITEC
E-coil bit noises. Array of 6 elements.
IECURR and FWTEC can be specified in K or SNAP files. Namelist IN1 in K files and namelist EFITIN in SNAP files. BITEC in K file IN1 only.

3. Optional boundary constraints

NBDRY
  1. of boundary points.
RBDRY
R of boundary points in m.
ZBDRY
Z of boundary points in m.
SIGRBD
R uncertainty array in m.
SIGZBD
Z uncertainty arrays in m.
FWTBDRY
fitting weight of boundary points.
Specified in K file IN1 or SNAP file EFITIN.

4. Optional vertical shifting of flux surfaces during fitting

FITDELZ=.T. to turn on.
Specified in K file INWANT or SNAP file EFITIN.

5. Optional inclusion of rotation. Must set KPRFIT=3 ICURRT=5, if no pressure data NPRESS=0

KVTOR
rotational switch,
0 = no rotation,
1 = approximate first order form,
2 = include second order terms,
3 = exponential form
NOMEGAT

OMEGAT
rotational frequency data array in rad/sec, need DMASS array
ROMEGAT, ZOMEGA
(R,Z) of rotational frequency data points in m
SIGOME
rotational frequency uncertainty array
KWWCUR
number of rotational pressure terms, for polynomial representation KWWFNC=0 only
WCURBD
1 = finite rotational pressure gradient at the boundary
0 = zero boundary gradient
SCALEPW
array of scaling factor for rotational pressure or rotational frequency. default scalepw(1)=-1
FWTPRW
array of fitting weights for rotational data. These are specified through namelist INVT in K files
NMASS
number of mass density point
DMASS
mass density in kg/m3
KWWFNC
basis function switch,
0 = polynomial,
6 = spline
KWWKNT

WWKNT
array of knot locations for spline basis function
WWTENS
spline tension:
0 = cubic spline,
large = piecewise linear
All inputs can be specified through namelist IN1 in K files
