MESSENGER: MASCS
May 12, 2017.
MESSENGER Release 16 includes several new MASCS
products as well as revisions to previously
released products. A VIRS tutorial is also provided
in the Document directory of the derived data
volume, and is listed below under Related
Information. See the
ERRATA.TXT
file in the top-level directory of
MASCS volume MESSMAS_2101 for details about this release
and previous releases.
The new and revised products in
this release are provided on a new archive volume,
MESSMAS_2101. The revisions are due to calibration
and data processing improvements; however, the
previous versions of the products will remain
available on volume MESSMAS_2001. See below for
links to both volumes.
The VIRS DDRs on the previously
released volume, MESSMAS_2001, contained an error
in the data which was reported on August 16, 2016
(see
ERRATA.TXT on MESSMAS_2001).
With this release, the DDRs on that volume have
been revised to correct the error.
The
MASCS Readers
(IDL procedures) have also been updated
for this release.

MASCS is the Mercury Atmospheric and Surface
Composition Spectrometer instrument on MESSENGER. The data sets are produced by
the MASCS Science Team at Johns Hopkins University
Applied Physics Laboratory, Laurel, Maryland.
MASCS has two subsystems, UVVS (Ultraviolet and
Visible Spectrometer) and VIRS (Visible and Infrared
Spectrograph). UVVS data are archived by the PDS
Atmospheres Node, and VIRS data are archived by the PDS
Geosciences Node. Both data sets are stored on the same
archive volume, available from both nodes.
