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
-
- 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
- number of rotational frequency data point
- OMEGAT
- rotational frequency data array in rad/sec, need DMASS array

- 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
