By right-clicking the cursor over a spectral plot, a window containing a tabbed pane with multiple functions is displayed. The exact appearance of the tabbed panes will depend on the spectrogram contents. Available panes may include:
A typical header browser window looks like this:
No editing is allowed in this window. This window is allowed for all spectrogram types.
An alternate view of the information stored in the spectrogram header can be seen with the Meta data browser:
The browser depicts selected meta data according to the IVOA SED Data Model specification.
No editing is allowed in this window. This window is allowed for all spectrogram types.
A typical data browser window looks like this:
The exact appearance of this window will depend on the spectrogram type and contents. Each column in the table displays one of the existing data arrays in the spectrogram (plus the Bin column generated internally by Specview). Floating point data is truncated for convenience, but individual values can be displayed at full precision using the tool tip (move the mouse cursor over the desired field and wait for a couple of seconds). Physical units applicable to each column can also be displayed using the tool tip over the column heading.
If columns get too packed and hard to read, they can be resized and moved at will by dragging the column headers sidewise. Of course, the entire window can also be resized. Note that if columns are moved around, the tool tip mechanism will not work properly.
No editing is allowed in this window. This window is allowed for all spectrogram types.
See in Sec. 4.3.1 how to do it.
This is typically the default color selector provided by the underlying Java libraries that support Specview. Its appearance may depend on the specific platform in which Specview is running.
By selecting any given color, the corresponding spectrogram segment is replotted with the new color.
This window is allowed only for spectrograms that were built with data coming from more than one instrument (or more than one file if it is SED data). Also, ISO spectra (Sec. 1.6.10) are plotted in multiple colors due to the complex nature of these spectrograms.
Read more about color plotting in Sec. 2.18.
The style selector looks like this:
A few line styles, symbol types, and symbol sizes are available. By selecting any one of them, the corresponding spectrogram segment is replotted with the new style.
This window is allowed only for spectrograms that were built with data coming from more than one instrument (or more than one file if it is SED data). Symbol style and size selection is allowed only for SED data.
