The Visual and Infrared Mapping Spectrometer (VIMS) is a instrument onboard the Cassini mission.
Instrument description
VIMS included a pair of imaging grating spectrometers that were designed to measure reflected and emitted radiation from atmospheres, rings and surfaces to determine their compositions, temperatures and structures.
Visible Channel [VIMS-V] (0.35 to 1.07 µm [96 channels]; 32x32 mrad field of view)
Infrared Channel [VIMS-IR] (0.85 to 5.1 µm [256 channels]; 32x32 mrad field of view)
Mass: 37.14 kg
Peak Operating Power: 27.20 W
Average Operating Power: 21.83 W
Peak Data Rate: 182.784 kilobits/sec
Dimensions: 78 cm x 76 cm x 55 cm
Downloading and processing VIMS data
Imagery
Tutorial
From the “Maps” tab, zoom-in on your region of interest. You can swith backgrounds for more visibility, and then display the VIMS layer. You can see the VIMS products footprints that appear in pink. Use the “Select” button to choose the products you desire over an area. Use the right-click context menu to add your selection to your workspace.

But given how dense and global is VIMS coverage, you might want to use the text search tab using keyworks "titan", "vims" and a coordinate.

In the "Workspace" tab, you will see your product selection. VIMS images are already processed by its science team, MarsSI directly provide the map-projected products (MRDR).
Check the product status: if some data is not already done yet, select the rows you would like to request by ticking the input on the left column (you can use the "Select all" button to select all visible products) and click on the "Process" action on the top of the workspace table. You can check more information about the processing in the job tab if needed.
Once all the data you would like is done, select entries by ticking the input on the left column (you can use the "Select all" button to select all visible products) and click on the "Copy" action to request a copy of the data in your personal directory. You can then proceed to download products as described in the SFTP section.
