     newname=. Set this to saves the new 3D E field to newname, otherwise will overwrite e_var.
     anglemin=. The min angle for E dot B = 0. 15 deg by default.
     no_preprocess=. A boolean, set to skip the interpolation and smoothing on b_var.

## RBSP_EFW_PHASEF_SPINFIT (PROCEDURE)

[Previous Routine] [Next Routine] [List of Routines]

     Adopted from rbsp_efw_phasef_spinfit, but changed the part to get sunpulse_times.

     NAME:
       rbsp_efw_phasef_spinfit (procedure)

     PURPOSE:
       Derive spin-fit E-field from instantaneous E-field measurements. The
       spin-fit model is as such:
               fit = A + B * cos(phi) + C * sin(phi)
       where B and C are E-fields in the DSC X and Y dimensions, and angle is the
       angle between the DSC X direction and the EFW spin plane boom used in the
       spin-fit derivation, as demonstrated below.

           DSC Y
                |       / EFW spin plane boom
                |      /
                |     /
                |    /
                |   /
                |  /
                | /
                |/)angle________ DSC X

       NOTES: 1. Similar to thm_spinfit.pro, this routine is a wrapper of
                 spinfit.pro for RBSP. Unlike thm_spinfit, this routine only works
                 on one tplot variable at a time.
              2. Normally, this routine saves four tplot variables, such as
                      'rbspa_efw_esvy_spinfit_a'
                      'rbspa_efw_esvy_spinfit_b'
                      'rbspa_efw_esvy_spinfit_c'
                      'rbspa_efw_esvy_spinfit'
                 where the first three are the three cooefficients from the fit and
                 the last one is like a normal EFW data type in DSC.
              3. This routine passes a [n,3] waveform to spinfit.pro for spinfitting.
                 spinfit.pro does stuff with all three components, but since we're only
                 interested in getting the RBSP spinplane spinfit field, the only
                 component that matters is the one you're interested in using to do
                 the spinfit.
