= Processing Notes for VFISV =

VFISV is the Very Fast Inversion of the Stokes Vector code optimized for use with the HMI observations.

 . The current version of the code is termed '''fd10'''. See the release notes for the [[ME720sfd10| FD10 version]] of the VFISV Code.
 . An earlier version of the codes was e15w1332

=== Milestones in fd10 processing ===

2013.04.30
 . Use of time dependent phase maps for HMI filter profiles
 . Improved phase maps reduce field strength and effects of fringes in the HMI wavelength filters.
  . CODEVER4 = 1.33; INVCODEV = "vfisv FD10 2013 Apr. 30; uses time-dependent HMI..."
  . Phase map used indicated in keyword INVPHMAP

2012.04.13
 . First pipeline version of fd10 code
 . CODEVER$ = 1.22; INVCODEV = "vfisv FD10 2012 Apr. 13"
