Interface to produce plots, listings, output files for IMAP spacecraft

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 IMAP data were made using IMAP high res data from from CDAWeb
1. The name mag data: 'IMAP_MAG_L2_NORM-RTN' (0.5sec resolution)
2. The name of plasma data - 'IMAP_SWAPI_L3A_PROTON-SW' ( 1-min. resoilution)
     Note2: Only arithmetic hourly averaging was done, (each hour includes all min. which are inside of this hour)

3. Trajectory data were taken from HelioWeb
