NEAR Data Set Structure
In PDS, a "data set" is a group of data under the same data set ID.
All the PDS NEAR data sets have this high-level directory structure:
| aareadme.txt | This text file provides an overview of the contents the data set. |
| browse | This directory contains browse tools developed by NEAR scientists for specific scientific inquires. This directory may not be present in all data sets. |
| calib | This directory contains files used to calibrate instrument data. This directory may not be present. |
| catalog | This directory contains PDS catalog files with descriptions for the mission, instrument host, instrument and data sets. |
| data | This directory contains uncalibrated or calibrated instrument data. |
| document | This directory contains instrument documentation. It is included only on the first volume of a set of data. For example, only the first volume of MSI data for the Eros Orbit phase has a document directory. |
| errata.txt | This text file describes data errors and anomalies. |
| geometry | This directory contains geometry files. It may include SPICE files. This directory may not be present. |
| index | This directory contains index tables describing times and key data file parameter values for this data set. |
| voldesc.cat | This text file contains a formal description of the contents of the volume. |
