NAME:
CORRECT_DELTA_PHI_TENSOR.PRO
PURPOSE:
Apply eclipse delta_phi corrections to L1 MOM tensor quantities.
CATEGORY:
TDAS
CALLING SEQUENCE:
correct_delta_phi_tensor, tens=mflux, delta_phi=delta_phi
INPUTS:
OUTPUTS:
KEYWORDS:
tens: An Nx6 input array representing the xx,yy,zz,xy,xz,yz
components of a 3x3 matrix. (The other three elements
are implied by symmetry.) The data is modified in place.
delta_phi: An array of delta_phi correction values, in degrees.
The sample counts of tens and delta_phi must match.
PROCEDURE:
For each sample: construct a 3-d rotation matrix corresponding
to a delta_phi degree counterclockwise rotation about the
DSL-Z axis. Construct a 3x3 matrix from the 6-element tensor
sample. Apply the rotation by performing matrix multiplication:
transpose(rotation) # tensor # rotation
Then strip the redundant terms of the result, yielding a
modified 6-element representation of the original tensor.

CORRECT_DELTA_PHI_VECTOR.PRO
PURPOSE:
CATEGORY:
TDAS
CALLING SEQUENCE:
correct_delta_phi_vector,tvar=thb_fgs_dsl,delta_phi=delta_phi
INPUTS:
OUTPUTS:
KEYWORDS:
tvar: name of an input tplot variable containing 3-d vectors in DSL.
The data will be altered in place.
x_in, y_in: Input data with X and Y in separate arrays. Output
goes to variables specified with the x_out and y_out keywords.
xyz_in: Input data with x,y,z in a single array. Data will be
altered in place.
delta_phi: Array of delta_phi values, in degrees. The sample
count must match the sample count of the data being transformed.
PROCEDURE:
Given a tplot variable name or array(s) of data values (in DSL coordinates),
and an array of delta_phi values, apply a counter-clockwise rotation of
delta_phi degrees. This is used to apply the eclipse delta_phi corrections
obtained from the spin model, and is intended for correcting spin fits (efs
and fgs), and (3-vector) particle moments. Waveform data
does not require this correction. Some of the quantities
from L1 MOM are tensors, and should not be corrected with this
routine -- see correct_delta_phi_tensor.

PURPOSE:
Check a spinmodel segment structure to ensure that the model parameters
b and c are consistent with the start and end times and
spin counts
CATEGORY:
TDAS
CALLING SEQUENCE:
segment_test,probe,segment,result
INPUTS:
probe: A single character probe letter (only used in output messages).
segment: A spinmodel_segment structure.
OUTPUTS:
result: 0 for failure, 1 for success
KEYWORDS:
None.
PROCEDURE:
Calls segment_interp_t to get spin count and spin phase at
segment start/end times.
Calls segment_interp_n to get sun pulse times of segment
start/end counts.
Cross check results of segment_interp_t and segment_interp_n,
verifying that interp_t and interp_n results are consistent
within modest tolerances (100 usec for times, 0.1 deg for
phase angles).
Check maxgap field against 4-hour threshold; large gaps are
likely a result of missing data.

Function: spinmodel_post_process
Purpose: Performs post-load corrections on spinmodel data.
Notes: Somewhat finicky about data requirements. Will throw an error that
causes interpreter to halt unless the error is explicitly caught. Error's
will be returned in the SPINMODEL_POST_PROCESS message block.
If you find execution halted here and you aren't sure why, it is probably
because the state support data was not loaded.
This occurs most commonly because
1. there is no data available on this day, or
2. because of internet connection issues,
3. because the !themis.no_download flag is on.
