Interface to produce plots, listings, output files for Parker Solar Probe(PSP)

This page provides the ability to plot or list (or create a file) of any selection of the parameters listed below.

COHO hourly and daily PSP data were made using PSP high res data from from CDAWeb
1. The name of plasma data - 'PSP_SWP_SPC_L3I',  parameters name -
     Proton bulk velocity, from 1-dimensional Maxwellian fitting, in the [inertial] RTN frame (Only Good Quality)
     [Total] proton density, from 1-dimensional Maxwellian fitting. (Only Good Quality)
     Proton radial [most probable] thermal speed component, from 1-dimensional Maxwellian fitting. (Only Good Quality)
         Note: Thermal speed was converted into Proton Temperature
2. The name mag data: 'PSP_FLD_L2_MAG_RTN_1MIN'

3. Trajectory data were taken from HelioWeb
