Radial and Non-Radial Solar wind velocities for C/2011 L4 (PANSTARRS)

This dataset was analysed and presented in the <b>‘Solar Wind Velocities at Comets C/2011 L4 Pan-STARRS and C/2013 R1 Lovejoy derived using a New Image Analysis Technique’ paper. Submitted to JGR - Space Physics.</b><br><br>Please contact the author at [e-mail] for info on the software. Only STEREO B data was successfully analysed for comet C/2011 L4 (PANSTARRS). STEREO A and Earth-based images are available but are not usable with this technique due to the low orbit plane angle. The difference images used in this study were made available for analysis by K. Battams (NRL).<br><br>Each difference image was processed through IDL using the main technique described in the paper to produce radial solar wind velocity estimates from the cometary ion tail of comet C/2011 L4 (PANSTARRS). The processed variables, including the final solar wind velocity results are stored as individual .sav files for each image.<br><br>To produce a plot, the solar wind velocities must be obtained from each image OR use the concatenated solar wind velocities saved as c2011l4_SWspeed_20140619.sav or the c2011l4_bundlepos_20140626.sav, which was created from a selection of images described in the paper to produce non-radial solar wind velocities for the Flow Vector Maps section described in the paper.
