Viewing Data

When a search is completed, you can view data about the object. What images are available are depend on what is on the form and what data is returned. For example, here we see

that there is a preview image of the data, an overlay of the apertures on a DSS image, and a raw DSS image of the object. For another record from the same search on the same for we may find

that there is no Preview image, but rather a spectral preview available.

DSS/Overlay images

Clicking on the Overlay button spawns the JAVA fits viewer, loads the image from the DSS server, and places the Space Telescope aperture outline on the images oriented according to the information in the database

Clicking DSS button will do the same without the apertures.

You can use JIPA to refine you coordinate searches. By right clicking in the JIPA window, the coordinate of your click will be sent back to the active form in StarView. Hence, in the above picture of M51, you could click on the companion galaxy to push its coordinates back to the active form to search around its center.

The JIPA tool has several features that you may wish to use. The Tools menu contains two items: Image processing to change the zoom and color map stretch for the panel,

and FITS Header to view the keywords from the file.

Preview Images

Clicking on the Preview button fetches the preview image of this dataset and views it in the FITS viewer

Preview Spectra

Clicking on Spectrum gets a spectrum preview. There is no general spectral FITS viewer in JAVA at this time. Currently, StarView retrieves GIF images of the spectral data originally generated by the IRAF splot routine.
