Fitting Mode Variables Specified in the IN1 Namelist

Many variables used in fitting mode represent data which is extracted from the shot data base and written into a K-file containing the IN1 and INWANT namelists by running EFIT with input mode 5. Values for these variables are typically never entered by the user.

BITEC "Bit E-coils". E-coil current physical unit equivalent to 1 digitizer count. (E-coil bit noises?) Array of 6 elements. Obtained from data and written into K-file. Ignored unless IECURR=2?
BITFC "Bit F-coils". F-coil current physical unit equivalent to 1 digitizer count. Array of 18 elements(?). Obtained from data and written into K-file. "Bit Ip".
BITIP Plasma current physical unit equivalent to 1 digitizer count. Obtained from data and written into K-file. Default = 0.0
BITMPI "Bit Magnetic Probes Internal". Magnetic probes physical unit equivalent to 1 digitizer count. Array of ? elements. Obtained from data and written into K-file. Default = all zeros
BRSP Current arrays; first 18 (NFCOIL) elements are F-coil currents in Amp-turns(?). BRSP not equal 0 for fixed F-coil currents. BRSP(NFCOIL+1) to BRSP(NFCOIL+KPPCUR) coefficients for P'. BRSP(NFCOIL+KPPCUR+1) to BRSP(NFCOIL+KPPCUR+KFFCUR) coefficients for F2. Default brsp(1)=-1020
COILS Flux loop signals in v-sec/rad. Obtained from data and written into K-file.
CURRN1 "Current N1". N1 coil current. Obtained from data and written into K-file. Default = 0.0
DENR "Density Radial". Radial line density. Obtained from data and written into K-file. Default = all zeros
DENV "Density Vertical". Vertical line density. Length 3 vector. Obtained from data and written into K-file. Default = all zeros
DFLUX "Diamagnetic Flux". Measured diamagnetic fluxes in mv-s. Obtained from data and written into K-file.
ECURRT "E Current". Vector of length 6 containing E coil section currents in Amps. The 6 sections are
  1. Central solenoid A, turns 1-48, pointname ECOILA
  2. Central solenoid B, turns 1-48, pointname ECOILB
  3. turns 49-52A + 60-61A, pointname E567UP
  4. turns 49-52B + 60-61B, pointname E567DN
  5. turns 53-59B, pointname E89DN
  6. turns 53-59A, pointname E89UP

This data is typically obtained from data and written into the K-file. For data obtained during shots prior to July of 1995 (when there were 2 E-coil sections rather than 6), EFIT will fill in internally setting ECURRT(3)=ECURRT(5)=ECURRT(1), and ECURRT(4)=ECURRT(6)=ECURRT(2). Default = all zeros.

ERRMIN "Error Min". Minimum convergence error before exit for ICONVR=2 option. If chi-squared on any iteration is larger than on previous iteration, then if relative error (maximum flux difference between successive iterations) < ERRMIN and chi-squared < (how much?), iterations stop. Default=0.01.
EXPMP2 Magnetic probe signals in T. Obtained from data and written into K-file.
FITSIREF "Fit Psi Reference". Fit value of reference flux
  • True = fit
  • False = use measured reference flux (psf1a for DIII-D) (Default)
FWACOIL "Fit Weight Acoil". (ADP ring) 0 = do not include measured data in fit (default)
  • 1 = include measured data in fit
FWTBP Fitting weight to make FF' and p' proportional
  • 1 = similar P' and FF' profiles
  • 0 = no such constraint (default)

Do not set FWTBP=1 if KPPCUR is not equal to KFFCUR.

FWTCUR "Fit Weight Current". Fitting weight for plasma current (fitting weight for plasma current, RL01 if use vessel)
  • 0 = do not include measured data in fit (default)
  • > 0 = include measured data in fit. The larger the number, the heavier the weight is put on the current data.
FWTDLC Fitting weight for diamagnetic flux
  • 0 = do not include measured data in fit (default)
  • 1 = include measured data in fit
FWTEC "Fit Weight E-coils". Length 6 vector, each entry of which is a fitting weight for E-coil currents. Ignored unless IECURR=2?
  • 0 = do not include measured data in fit (default= all 0.0's)
  • 1 = include measured data in fit
FWTFC "Fit Weight F-coils". Length 18 vector, each entry of which is a fitting weight for F-coil currents.
  • 0 do not include measured data in fit (default = all 0's)
  • >0 include measured data in fit with weights defined by FWTFC entry
FWTGAM "Fit Weight Gamma". Length 16 vector, each entry of which is a fitting weight for polarimetry (MSE), 0 or 1.
  • 0 = do not include measured data in fit (default)
  • 1 = include measured data in fit

Default = all 0.0's

FWTMP2 "Fit Weight Magnetic Probes 2" Length 60 vector, each entry of which is a fitting weight for inner magnetic probes, 0 or 1.
  • 0 = do not include measured data in fit (default)
  • 1 = include measured data in fit
FWTSI "Fit Weight Psi". Length 41 vector, each entry of which is a fitting weight for flux loops, 0 or 1.
  • 0 = do not include measured data in fit (default)
  • 1 = include measured data in fit
LOOKFW "Look in Fitweight". Replace nonzero weights specified in user input FWTMP2 and FWTSI with weights from the file FITWEIGHT.DAT. This file contains 0 weights for probes and flux loops known to be broken at the time of the shot ISHOT and 1 for all others. Zero weights in user input are not modified.

>0 replace nonzero entries in FWTMP2 and FWTSI with corresponding entries from FITWEIGHT.DAT (default). <=0 Do not replace.

ISHOT shot number to analyze. Default=-1
PSIBIT flux loops, physical units corresponding to 1 digitizer count. Obtained from data and written into K-file. Default = all zeros
SIGDLC Standard deviation of diamagnetic flux measured data in mv-s.
ZELIP "Z Ellipse". Z of ellipse center in m for current initialization. If ZELIP > 105 then ZELIP is estimated from probe signals in same manner as Zp(?) and EELIP is set to 1.5. Fitting mode only. Default=0.0
