NAME: rbsp_despin (procedure) PURPOSE: Rotate data from a spinning frame to DSC. By default, the spinning frame is assumed to be the UVW frame. CATEGORIES: CALLING SEQUENCE: rbsp_despin, sc, tvar, angle_offset = angle_offset, pertvar = pertvar, $ newname = newname, uvw = uvw, xyz = xyz, offset_name = offset_name, $ no_axial_processing = no_axial_processing, $ no_offset_remove = no_offset_remove, $ tper = tper, tphase = tphase ARGUMENTS: sc: (In, required) Spacecraft name. Should be 'a' or 'b'. tvar: (In, required) Tplot variable to be despun, such as 'rbspa_mag_uvw'. KEYWORDS: angle_offset: (In, optional) Angle offset additional to spin phase. For UVW, angle_offset is 10 degree, which is the default. pertvar: (In, optional) Spin period tplot data. By default, pertvar = 'rbsp' + strlowcase(sc[0]) + '_spinper'. newname: (In, optional) New name for the despun data. By default, newname = tvar + '_dsc' /uvw: Shortcut for rotating UVW data. /xyz: Shortcut for rotating XYZ data. Equivalent to set angle_offset = 45. offset_name: A tplot name for saving offsets in spin-plane components. /no_axial_processing: If set, axial component is not processed. By default, the first spin-tone harmonic is removed in the axial component. /no_offset_remove: If set, offsets in spin-plane components are not removed. tper: (In, optional) Tplot name of spin period data. By default, tper = pertvar. If tper is set, pertvar = tper. tphase: (In, optional) Tplot name of spin phase data. By default, tphase = 'rbsp' + strlowcase(sc[0]) + '_spinphase' Note: tper and and tphase are mostly used for using eclipse-corrected spin data.

Added tper and tphase to use eclipse-corrected spin data. 2. Added keyword *no_offset_remove*.
