Routine Descriptions

 e_var. The tplot var saves 3D E field in certain coord.
 b_var. The tplot var saves 3D B field in the same coord.
 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.

 This is to easily switch among servers to download requested CDF.
 Adopted from rbsp_load_wake_effect_cdf_file.
 This program is supposed to be updated frequently during the phasef tests.

 time. The time range in unix timestamp.

 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.

   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.
