==============================================================================
Overview:
==============================================================================
This data set contains instrument raw data from the Navigation Camera
(NavCam) onboard the ROSETTA spacecraft (S/C) from the Escort Phase.
The time interval starts on Jul, 26th 2016 and ends on Aug, 9th 2016.
The frequency of the navigation slots is of one 2x2 raster with four images
every five hours. This nominal frequency can be interrupted by manoeuvres.
Onboard the Rosetta Orbiter (RO) there are two identical NavCams, providing
complete redundancy, in the event of Single Point Failure (SPF). Each NavCam
unit consits of a Camera Baffle (CAM-BAF), Camera Optical Head (CAM-OH) and
a Camera Electronics Unit (CAM-EU) and is capable of providing multiple
operating modes to fully satisfy the requirements of the Rosetta mission with
respect to the autonomous tracking and attitude determination.

ESC2-MTP015 NavCam Data Archive:
==============================================================================
a) S/C Data
=========================
CODMAC Level / Type Data Type Data Content
2 / EDITED Data Image RAW TM of HK and IMAGE Data
The data can be found in the following directory:
*/DATA/
The data products are in the form of RAW images each with a detached label
file that contains a cropped version of the Housekeeping (HK) - Telemetry (TM)
information.
b) Supporting Files
=========================
Supporting files for the Archive end user include PDS: documentation,
descriptions and searchable indices. These are organised into three sub-
directories immediately below the root directory:
- CATALOG
- DOCUMENT
- INDEX

The ROSETTA project decided that the data would be archived in the PDS Version
3 format and, consequently, the layout of this volume and all associated label
files for each file conform to the PDS / PSA guidelines.
