|
DATA_SET_DESCRIPTION |
Required Reading
================
The format of all Alice data are described in detail by the EAICD
document located in the /DOCUMENT directory. In addition, the
Rosetta Alice logbook file, RA_LOGBOOK_NNN.ASC, also located in
the /DOCUMENT directory provides observational details such as
observation target, commanded exposure time, etc., for all Alice
data. The Alice team strongly recommends reading this
documentation before using the data.
Data Set Overview
=================
This data set contains unprocessed data acquired by the Rosetta
Orbiter ALICE UV Spectrometer during the first earth swing-by
phase of the Rosetta mission, which occurred October 17, 2004 to
April 4, 2005. Observations of calibration targets were made
during this mission phase. A detailed listing of all Alice
observations is given in the observation log file located in the
DOCUMENT directory.
Processing
==========
The data in this data set are unprocessed, CODMAC Level 2 data.
No calibration or data processing have been applied. In the Alice
file nomenclature, this is noted by the 'ENG' in the filename.
Data
====
The data are in FITS format and text format. Each FITS file
has a detached PDS label so that they can be read either by
FITS or PDS tools. A detailed description of the data format
is given in the ALICE EAICD document located in the DOCUMENT
directory of this data set.
Ancillary Data
==============
No ancillary data included in this data set.
Coordinate System
=================
There is no particular coordinate system associated with this
data set.
Software
========
All FITS readers should be able to successfully read the data.

CONFIDENCE_LEVEL_NOTE |
Confidence Level Overview
=========================
Data confidence is nominal, meaning that all data have been
validated by the Alice team and found as expected. Any exceptions
are noted by the DATA_QUALITY field in the label files.
Review
=====
Rosetta internal archive review Jan 2006.
Formal review process Jan 2007.
Data Coverage and Quality
=========================
Data quality is good unless otherwise noted by the DATA_QUALITY
keyword.
Limitations
===========
These data are raw and unprocessed and thus are not in physical
units. The proper calibration procedures need to be applied
before the data can be used for the vast majority of scientific
purposes.
