Shock database selection

Build your shock database.
To see a list of all available data, click 'Submit' without selecting anything.
To limit and specialise your database, select any spacecraft or mission, and/or adjust any parameter range, before clicking 'Submit'.
If 'Include missing values' for a certain parameter is unchecked, shocks where the corresponding parameter value is missing will not be included.
Note: It is not recommended to use the 'back' and 'forward' buttons on your browser, as the website may not work properly using them.

Observing spacecraft(s): MMS Cluster THEMIS (If none selected, all will be included.)

Data mode: Only shocks including burst mode data All data

Direction: Inbound Outbound (If none selected, all will be included.) Include missing values

Adjust one or more parameter ranges:
(The pre-filled default values correspond to the lowest and highest values in the current database.)

		Lower limit	Upper limit
	Date / time range			Include missing values
ΔR	Separation between observations of same constellation min mean max	km	km	Include missing values

Mf	Shock fast mode Mach number			Include missing values
θBn	Angle between the shock normal and upstream magnetic field	deg	deg	Include missing values
|Vus|	Plasma velocity magnitude upstream of the shock	km/s	km/s	Include missing values
|Bus|	Magnetic field magnitude upstream of the shock	nT	nT	Include missing values
