Volume MSLRAD_1002: MSL RAD Reduced Data
1. Introduction
This volume contains RDR data (Reduced Data Record) from the Radiation
Assessment Detector (RAD) instrument aboard the Mars Science Laboratory
(MSL) rover, better known as Curiosity. The data files contain radiation
measurements taken during interplanetary cruise and the surface mission.
The RDR data are NASA Level 1A data that mirror the raw instrument
data obtained from telemetry.
The volume also contains calibration data and documentation useful for
the interpretation of the data.
For more information about the data and about this volume, refer to the
documentation in the DOCUMENT and CATALOG directories of the volume.
2. Volume Format
These RDR data products are being delivered electronically to PDS. They
are archived in a single volume which will continue to grow as the
mission progresses.
3. File Formats
Data File Format
The RDR data files are calibrated data reconstructed from EDR data and
formatted according to the RAD RDR Software Interface Specification
(RDR SIS). The file naming convention is explained in the RDR SIS,
which is in the DOCUMENT directory of the volume.
The RDR files are in ASCII format. The files are in generally
human-readable form, but some lines are very long to preserve
machine-readability as well.
Each data file is described by a detached PDS label as described below. The
fields in the data files are described by PDS format files (*.FMT), which are
referenced in the labels. The format files are in the LABEL directory of
this volume.
Document File Format
Most of the documentation for this volume resides in the DOCUMENT and
CATALOG directories. The CATALOG directory contains PDS catalog files
(*.CAT) providing information about the spacecraft, instrument, data set,
personnel associated with the experiment, and relevant literature
references. The catalog files are in ASCII format. The DOCUMENT
directory contains the Software Interface Specification (SIS) document
describing the RDR data, and the Volume SIS describing the volume structure.
Documentation files also exist in most of the top-level directories
ASCII information files (*INFO.TXT) exist in many of the directories on
this disk; these files describe the directory contents.
ASCII text files ion this volume have records delimited by a carriage
return character followed by a line feed character. This line ending
makes the file easier to read on a variety of operating systems.
PDS Label Format
All data and tabular files in this volume have associated PDS labels.
A PDS label provides descriptive information about the content and
format of the associated file. The PDS label is an object-oriented
structure consisting of sets of "keyword = value" declarations. The object
to which the label refer (e.g. IMAGE, TABLE, etc.) denotes the form:
^object = location
in which the caret character (^, also called a pointer in this context)
indicates where to find the object. In an attached label, the location is
an integer representing the starting record number of the object (the first
record in the file is record 1). In a detached label, the location denotes
the name of the file containing the object, along with the starting record
or byte number, if there is more than one object in the file.
For example:
^HEADER = ("F01.IMG",1)
^IMAGE = ("F01.IMG",1025 ❮BYTES❯)
indicates that the IMAGE object begins at byte 1025 of the file F01.IMG, in
the same directory as the detached label file. Below is a list of the
possible formats for the ^object definition.
^object = n
^object = n❮BYTES❯
^object = "filename.ext"
^object = ("filename.ext",n)
^object = ("[dirlist]filename.ext",n)
^object = ("filename.ext",n❮BYTES❯)
^object = ("[dirlist]filename.ext",n❮BYTES❯)
where:
n is the starting record or byte number of the object, counting from
the beginning of the file (record 1, byte 1);
❮BYTES❯ indicates that the number given is in units of bytes;
filename is a maximum 36-alphanumeric upper-case character file name,
ext is the 3 upper-case character file extension;
dirlist is an upper-case, period-delimited path-list of parent
directories, beginning at the directory level below the archive volume
root directory, that specifies the object file directory (used only
when the object is not in the same directory as the label file).
Detached label files have variable length lines with an end-of-line
designator consisting of a carriage return character followed by a line
feed character. This makes the files easy to read on a variety of
different operating systems.
Catalog File Format
Catalog files (suffix .CAT) exist in the root and CATALOG directories.
They are formatted in an object-oriented structure consisting of sets of
"keyword = value" declarations.
4. Volume Contents
The files in this volume are organized in one root-level directory with
several subdirectories. The following outline shows the structure and
content of these directories. In the table, directory names are enclosed
in square brackets ([]), upper-case letters indicate actual directory or
file names, and lower-case letters indicate the general form of a set
of directory or file names.
