PROCEDURE: thm_part_sphere_interpolate PURPOSE: Interpolate particle data to match the look direcitons of another distribution INPUTS: source: A particle dist_data structure to be modified by interpolation to match target target: A particle dist_data structure whose look directions will be matched OUTPUTS: Replaces source with a spherically interpolated target KEYWORDS: error: Set to 1 on error, zero otherwise NOTES: #1 Interpolation done using IDL library routine "griddata" #2 This code assumes that source & target have been time interpolated to match each other This has a ton of TBDs, we need to come back and fix them when time is available. With TBDs this code will not have general purpose utility...
