2021.
Release of APXS Oxide
Abundance data through the end of mission, updating the previous delivery from
2016.
This data set contains oxide abundance
data derived from the APXS Reduced Data Record (RDR)
products acquired by the Alpha Particle X-ray
Spectrometers on both MER rovers. The data were provided by
Ralf Gellert, University of Guelph, and Rudolph Rieder,
Max Planck Institute, and archived by the PDS
Geosciences Node.

accompanied by a PDS label that defines the table columns. The tables are in
comma-separated-value (CSV) format, viewable in any text editor and suitable for
loading into a spreadsheet program such as Microsoft Excel.

CATALOG Directory
- Files in the CATALOG directory are text files
containing documentation formatted for reading by humans and by software. The files
contain information about the data set,
the instrumentation, references, and
personnel involved in archiving the data. See the file
CATINFO.TXT for details. These files are called catalog
files because they are entered into the PDS Catalog for online searching.
|
DOCUMENT Directory - The DOCUMENT directory has notes from the APXS
Payload Element Lead. These notes contain important
caveats regarding the use of the data. Read these notes carefully to avoid
misinterpretation of the data.
|

- The INDEX directory contains a PDS index table for this archive. See
the file
INDXINFO.TXT for additional details.

INDEX.TAB
- A list of the products in this archive, their path and file names
relative to the root directory, and the product creation time. This file is described by the label
INDEX.LBL.

EXTRAS Directory - The EXTRAS directory
in a PDS archive contains ancillary
material that may be useful but is not required for the understanding of the
archive. In this archive, the EXTRAS directory contains the original Excel
spreadsheets as submitted to PDS, which became the basis for the tables in the
DATA directory described above. The contents of this directory are described in
EXTRINFO.TXT.
