The DSDSweb control interface is shown in the figure below. Clicking on the plot will take you to a description of a particular control.
The pull down menu allows you to select the spacecraft and plot type to be displayed. More information on each of the currently available plot types is given on the Quicklook Plot Descriptions page. The change will take place the next time the Submit or one of the selection buttons is pressed. Only a single plot type can be selected for display at a time but it is possible to have several browser windows each showing different plot types.Back to Interface
This control will select and request the next plot type (equivalent to using the pull down menu and then pressing Submit). Under normal conditions the cycle control will loop through groups of plots, so for example the three-hour quicklook plots will cycle through; Overview, Fields and Waves, Particles and then back to the three-hour Overview.Back to Interface
Once changes have been made to the Plot Type, Number of Plots etc. The Submit button can be used to apply these changes and request the required plot from the server.Back to Interface
Use the Year, Month and Day pull down menus to select the date of the plot being requested. You must use the Submit button to apply the changes and request the new plot.Back to Interface
Use the Period pull down menu to select the three hour period to be displayed. This option is only relevant to those plot types for which there is more than one plot per day (three hour quicklook plots).Back to Interface
This will display the earliest plot available for the currently selected typeBack to Interface
These controls are used to select the previous plot. Normally only the standard (<) control is displayed which will step back one plot. Please note that in this context the previous plot is in terms of the time sequence and not the plots that have previously been displayed. You can use your browsers 'Back' button to look at previously displayed plots.
The block previous (<<) control will only be shown when the number of plots setting (see Advanced Features) is greater than one. In this case the standard (<) control will just shuffle the plots back by one, adding one new plot at the start and dropping the last plot from the bottom. The (<<) control will rewind by the number of plots on the page so that the last plot on the new page will correspond to the plot just prior to the first plot on the current page.Back to Interface
These controls are used to select the next plot. Normally only the standard (>) control is displayed which will step forward one plot.
The block next (>>) control will only be shown when the number of plots setting (see Advanced Features) is greater than one. In this case the standard (>) control will just shuffle the plots forward by one, adding one new plot at the end and dropping the first plot from the top. The (>>) control will go forward by the number of plots on the page so that the first plot on the new page will correspond to the plot just after the last plot on the current page.Back to Interface
This will display the latest plot available for the currently selected type except in the case of the predicted position plot, where the plot corresponding to the most recent quicklook data will be shown. The forward and date controls can be used to look at the predicted position beyond this date. See also 'Latest' under advanced features.Back to Interface
The Reset control returns the plot number and size settings to their default values and selects the latest 3-hour Overview plot.Back to Interface
By default a single plot is displayed at a time and the date selection or forward/backward controls are used to select a different plot period. By typing a number between 2 and 50 a sequential set of plots will be displayed as a single document (note that all plots will be of the same plot type).
When the number of plots is greater than one, two additional buttons will be displayed ( <<, >> ). These can be used for navigating blocks of plots.Back to Interface
This option can be used to vary the relative plot size and can take a value between 0.01 and 4.0. This can be used in conjunction with the Number of Plots option to fit more plots on a page or if you are comparing with data from another source in order to get the scales to match. Please note that this works by changing the HTML <IMG> WIDTH attribute, which means that the re-scaling of the image is done within the client browser. Setting the size value much below 1.0 results in considerable degradation of the plot quality (though this is regained when the page is actually printed). There is no transfer time advantage of reducing the plot size since the full size image is always transferred over the network.Back to Interface
The 3-hour and whole orbit quicklook plots are inter-linked. This means that clicking inside the plot will automatically take you to the same plot type at the alternative resolution. The links are only active when a single plot is displayed and size information is not currently retained. In the case of multi-plot pages, clicking anywhere on a plot displays just that plot.Back to Interface
Just below the plot panel are a series of active links. These are set-up to point to other data resources that may be of interest to a DoubleStar investigator. Where possible date information is passed from the quicklook system to the remote resource so that data for the corresponding period is displayed. Links to the CSDSweb and DDMS servers will soon be added .
Near Real Time: Solar
Images from SEC | ACE Solar Wind | DST
SPOF KP Survey Plots: IMAGE orbit | Polar data | Geotail | IMP 8 | Wind | Wind 27 day
Ground-Based: GBDC Summary Plots | Satellite Situation Centre: Graphics | Tabular | Query
Solar images are received in near real time by the Space Environment Centre provided by the US National Oceanic and Atmospheric Administration (NOAA).
This is another near real time service provided by SEC. In this case solar wind data taken from the ACE spacecraft located at the L1 position is available in plots with time scales ranging from two hours to seven days. Links are provided to other ACE web sites from which browse products and level 2 data can be obtained.
This link takes you to the Dst service provided by the WDC-C2 for Geomagnetism at Kyoto. This service provides near real time, provisional and final sets of the Dst index.
Key parameter and orbit plots from a number of current ISTP missions are available from the NASA Science Planning and Operation Facility (Goddard Space Flight Centre).
The Cluster Ground Based Data Centre provides a portal to a large number of on-line plots provided by ground based instruments located around the world. The GBDC portal automatically resizes and positions the plots so that the time scales line up when viewed in a browser.
This is another service provided by the NASA/SPOF. It provides an extensive range of facilities for generating orbit plots, ground track information and field line tracing. Orbit information is included for all current ISTP missions and the Query option can be used to look for conjunctions between two or more of these spacecraft (plus groundbased instrumentation).
