BROWSE INSTRUCTIONS:

• All times are Universal Time unless labeled otherwise.
• The Execute button must be pressed in order to make changes in the display.
• The Image width option (in pixels) allows the user to scale the size of the browse images.
• The native size of the browse imagery is 576 x 512 pixels.
• If you select a value < 180, a thumbnail image is used whose native size is 128 x 128 pixels.
• The number of Rows and Columns in the spread sheet can be adjusted to a maximum of 4.
• The Interval setting will have a different affect, depending on the Table Type selected.
• When Table Type is set to Column Compare, Interval is the time interval between rows.
• When Table Type is set to Stream, Interval is the time interval between successive images.
• There are two Table Types.
• Column Compare allows a different image type to be selected for each column. Column one is the control point for the time constraint, i.e., when the interval is set to one hour, an image for column one is found (at least) one hour from the previous rows column one. The images in the other columns are the next images, of the selected type, found after the column one time.
• Stream creates a sequence of images of a single image type. The image in row one, column one, controls the image type and the start time for the sequence.
• < Step will shift the spread sheet view towards later data.
• Step > will shift the spread sheet view towards earlier data.
• Stepping up and down in the data base with these buttons may not have symetric results, depending on the temporal distribution of the data.
• There is a slight complication that may arise when using these buttons -- using the your browsers Back button immediately afterwards will give unexpected results.
• When Latest is checked, the first row always displays the latest data in the data base.
• To start the spread sheet on a date and time of your choosing, deselect Latest, and enter your time parameters: Y=year, M=month, D=day, H=hour, M=minute.
• The Image Type displayed in each column can be selected from the drop list.
• Meta Data for each image is displayed in a drop list, to compare a particular parameter between images, use the drop list to select that item in each image you are comparing.
