Table Display

The Layer control window provides a Show Table button, which will bring up a window with a tabular table display. For small tables, the entire table is displayed with scrollbars. For very long tables, this switches to a page jump-scrolling mechanism. When the user selects a region, any active table display layers will search their data to find sources in the region and highlight them in the displayed table (and on the image through another event mechanism). For large tables, the Show Selected button will jump between hightlighted records.

Tables can also have "active" fields. These fields have embedded data or URL references and are shown in blue. When the cell is selected these references are used as links to retrieve additional data.

For the URL links (e.g. for NED detailed source data), selecting the field brings up a new window in your default Web Browser and passes it the URL to fetch and render.

For data links, Oasis will handle the data retrieval and will then process the returned object as appropriate (display it if it is an image, overlay it if it is a table or drawing, fire up an XY plotter if it is a spectrum, light curve, etc.).

For more details, see the ASCII Table format write-up.

Selected data records (whether selected by the user or marked because of source selection in the image/overlay display window) can be saved to local disk as a new table file.

All this functionality (including the external data references) work just as well with table files loading in from the users own disk.
