ward) completes orthogonal RHS XYZ
'Phism', translate into FAC using azimuthal Solar Magnetospheric vector.
(See themis/spacecraft/particles/data_cache.pro)
uthal Solar Magnetospheric vector.
Phism is "phi" vector of satellite position in SM coordinates.
Y Axis = on plane defined by Phism-Z, normal to Z
Second coordinate definition: X = Phism x Z
Third completes orthogonal RHS XYZ
'mPhism', translate into FAC using azimuthal Solar Magnetospheric vector.
mPhism is minus "phi" vector of satellite position in SM coordinates.
Y Axis = on plane defined by Phism-Z, normal to Z
Second coordinate definition: X = mPhism x Z
Third completes orthogonal RHS XYZ
'Ygsm', translate into FAC using cartesian Ygsm position as other dimension.
Y Axis on plane defined by Ygsm and Z
First coordinate definition: X = Ygsm x Z
Third completes orthogonal RHS XYZ
Example:
fac_matrix_make,'tha_fgs',other_dim='Xgse',pos_var_name='tha_pos',out_var_name='tha_fgs_fac_mat'
function: thm_interpolate_state
Purpose: interpolates the low res STATE file
all variables are structures as produced by get_data
keywords:
Examples:
tha_spinper_highres=thm_interpolate_state(thx_xxx_in=thx_xxx_in,thx_spinper=thx_spinper) --> linear interpolation
tha_spinphase_highres=thm_interpolate_state(thx_xxx_in=thx_xxx_in,thx_spinper=thx_spinper,thx_spinphase=thx_spinphase) --> phase constructed according to the nearest neighbor spin phase, spin period
tha_spinras_highres=thm_interpolate_state(thx_xxx_in=thx_xxx_in,thx_spinras=thx_spinras) --> linear interpolation
tha_spindec_highres=thm_interpolate_state(thx_xxx_in=thx_xxx_in,thx_spindec=thx_spindec) --> linear interpolation
tha_spinalpha_highres=thm_interpolate_state(thx_xxx_in=thx_xxx_in,thx_spinalpha=thx_spinalpha) --> linear interpolation
tha_spinbeta_highres=thm_interpolate_state(thx_xxx_in=thx_xxx_in,thx_spinbeta=thx_spinbeta) --> linear interpolation
tha_pos_highres=thm_interpolate_state(thx_xxx_in=thx_xxx_in,thx_pos=thx_pos) --> spline interpolation
tha_vel_highres=thm_interpolate_state(thx_xxx_in=thx_xxx_in,thx_vel=thx_vel) --> spline interpolation
Notes: under construction!!
