ARTEMIS Observations of Plasma Waves in Laminar and Perturbed Interplanetary Shocks: Shock Parameters

Table of interplanetary shock parameters for the events in "ARTEMIS Observations of Plasma Waves in Laminar and Perturbed Interplanetary Shocks", by the same authors, submitted to the Astrophysical Journal (currently under review; manuscript # AAS27604R1). Parameters were calculated from WIND and ARTEMIS observations. Note that WIND is located at L1, and interplanetary shocks can evolve between L1 and the near-Earth environment, resulting in potentially different values for the shock parameters. Averages for values were taken a upstream and downstream of the transition region during 3-5 minute intervals where values were roughly steady and not near the transition region. Analysis was done in the spacecraft frame. Further information can be found in the paper listed above (doi link pending). Columns include the Satellite whose observations were used for the calculation for a given row (Satellite), the date of the shock event (Date), the upstream plasma beta (Beta_up), the ratio of downstream (dn) to upstream (up) average magnetic field (Bdn/Bup), ion density (Ndn/Nup), electron temperature (Tedn/Teup), and ion temperature (Tidn/Tiup), the change in velocity caused by the shock (Vdown-Vup; km/s), the shock normal in Geocentric Solar Elliptical (GSE) coordinates (Shock normal; GSE), the shock angle with respect to the background magnetic field (Theta Bn; degrees), the shock speed (Vshn_up; km/s), the Alfven (M_A), fast (M_f), and the first critical Mach numbers (M_cr), and lastly the ratio of the fast mode to the critical Mach numbers (M_f/M_cr). Error estimates are included. Calculation of parameters made use of the Rankine-Hugoniot equations. Grey highlights signify the parameters used in the accompanying paper.
