NAME: 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.
