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.

errata.txt This text file describes data errors and anomalies.
