The following topics will aid your search through the NEAR Data Archive:

Where can I find...? provides information to help you locate data, shape models, browers, surface features of Eros and Mathilde, etcetera.
The NEAR documentation set provides one-stop access to all mission documents, instrument documents, observing logs, and data set descriptions.
Mission phases presents a table of date ranges and durations.
Data levels defines the different types or levels of process data found in the archive>.
Naming scheme defines the naming convention used for NEAR data volumes.
Directory structure describes the directory structures within NEAR data volumes.
Known and discovered problems lists discrepancies found in the final NEAR delivery.

Level 2 Calibrated Data

The calibrated data consist of the highest-time-resolution, science-quality, magnetic field vectors and associated spacecraft position vectors. Data are organized by day and in tabular, ASCII format.

Calibrated data for the Cruise 1 and Eros On-Surface phases were not included in the archive. Each NEAR instrument team got to decide if it wanted to drop data when doing the calibrations.

Calibrated data for each day are provided in 2 coordinate systems: EROS Body Fixed (table file names beginning with "EBF") and NEAR-Sun-Orbital (table file names beginning with "NSO").

Level 3 Browse Tools

The Magnetometer team developed various web-based tools to browse JPEG renditions of calibrated data.

Browse tools for the Cruise 1 and Eros On-Surface phases were not included in the archive. Each NEAR instrument team got to decide if it wanted to drop data when doing the calibrations.
