Much of this information is necessary for understanding and viewing the cube. In particular, the label contains the offset to the cube, the dimensions of the cube, axes labels, and explicit wavelength information. NIMS Guides NIMS Guides provide descriptive information about each orbit, the planned observations within each orbit and the data return. The observation description includes planned geometry and observation intent. The guides are in PDF format, by chapter.
Many chapters are large and require significant time to download.
The Unix versions are available from the USGS Astrogeology team. Images from NIMS cubes and tubes can be viewed with any image display program which allows an offset from the beginning of the file to the selected image. Some editors do not recognize the PDS line termination conventions.
