Cruiser is a multi-spectral image data explorer with precise interactive blending of solar image series across time and wavelength domains. Scrolling in two dimensions enables discovery and investigation of similarities and differences in structure and evolution across multiple wavelengths.
The play button will play a movie in time or wavelength, depending on the time/wave button selection. The speed slider controls play speed. The numerical value shown next to the speed slider represents playback speed as a multiple of real time.
Clicking the blink button will bounce the wavelength cursor between a pair of wavelengths closest to the wavelength cursor.
Mutually exclusive button pairs are shown with a small white arrow across their border. A blue background indicates an active selection, while a dark gray background indicates the inactive option.
The media controls are placed below the time axis, or to the right of the wavelength axis depending on the image dimensions, to maximimize image size within the browser window.
Clicking the browser's page reload button will restart cruiser with the currently selected observation as a new session, resetting all selectable options to their default values.
In IOS, the pinch to zoom gesture can be used in the image area to zoom the entire page. If the page is zoomed to an extent that the image covers the entire viewable screen, the page can be scrolled using two fingers (one finger motions on the image moves the time and wavelength scrollbars.)
Observations can be downloaded for offline viewing. Display the desired observation, then hit the lowercase "o" key to save to offline storage. The Browse Data table appends the symbol ☑ to observation rows available for offline viewing. All available wavelengths are downloaded to offline storage. Hitting the uppercase "O" key will remove the currently displayed observation from offline storage. The amount of storage available varies by browser and configurations. This feature is intended to store a small number of observations, not large archives. This feature is not yet supported in current versions of Safari, but based on developer preview versions, will be supported in a future release of Safari.
