Flux

HET/LET particles are required to penetrate into at least two separate detectors before being accepted for analysis. The energies deposited through ionization loss in the detectors are the basic analysis variables.

See Voyager CRS Instrument Overview for details on the HET, LET and TET telescopes including instrument diagrams and nomenclature. (opens in a new window)

Using the Flux Interface

Spacecraft: Select V1, V2, or V1 & V2.
Select the check box next to Z > 2 for the heavy element (Boron through Nickel) fluxes. When checked a new element selection row will appear. Choosing an element will display an energy bin selection box. Long, multi-year, plot time periods and long averaging periods work best with the heavy elements.
Start Time and End Time: Enter the time period of interest. The end time of available data is shown on page initialization. Note: Hours and Minutes are set to zero (0) for the Start and End times (e.g. an End Time of 2020/01/20 is interpreted as 2020/01/19 23:59:59).
Averaging: 24-hour averages are the default, however, you may choose to calculate other averages by selecting other and entering the averaging value. Moving averages may also be entered in the next box.
Autoscaling and a Logarithmic Y-axis are default settings but you may turn them off. Turning off Autoscale allows you to enter your own y-axis limits.
Fluxes in the table are selected with your left mouse button. Use ctrl mouse-click to select multiple energy bins or to deselect. 1-3 fluxes per figure is usually best depending on average interval and time scale.
Select the Plot button to generate figures.
The Print button opens a new print window.
To generate data listings choose a Time Format and press the Listing button for links to downloadable data files.
The Next and Prev buttons time step forward and backward the same amount of time as your original selection.
The Home button resets the interface.
The Spectra and Rates interfaces may be accessed using the links in the upper left and right corners.
