OPUS Updates for September 2019 - Preprogrammed Ranges

This month we are pleased to bring you a new feature that aids in searching on ring radius or wavelength.

Preprogrammed Ranges

Users often need to search for standard ranges for ring radius, such as the inner and outer limits of Saturn's A ring or the semimajor axis of Enceladus. A similar problem occurs for wavelength; a user may wish to search for "blue" images but have to look up exactly what wavelengths that corresponds to. Both of these problems are now solved by the existence of preprogrammed ranges. When you click on the "Min" input box of the Observed Ring Radius field (available under Ring Geometry Constraints), a dropdown box will appear with a large selection of satellite semimajor axes and ring limits for Jupiter, Saturn, Uranus, and Neptune. Simply clicking on one of these options will fill in both the minimum and maximum value:


Alternatively, you may start to type the name of a feature, and the list of options will be limited to those that contain the string you've typed:



If only a single result is left, hitting ENTER will automatically fill in the values.

A similar feature is available for the Wavelength field, with colors taken from the PDS4 dictionary, CRC, and Johnson UBV filters.

As always, we welcome your feedback.
