COHO Voyager1 Scatter plots and linear regression fits

Cohoweb Data Explorer - Near-Earth Heliosphere Data - NSSDC - Goddard Space Flight Center

Interface to produce scatter plots and regression fits, or listings

Note: Voyager magnetometer data past 1989 must be used very carefully due to the very low magnetic field values being measured as compared to the pre-launch magnetometer accuracy requirements. Please click here for details.

For Advanced Options: For Linear Regression Fits (LRF) and scatter plots for single lag (including zero lag) and
for LRF for series of lags, for auto- and cross-correlation functions.click HERE
