Abstract
========
The Mercury Dual Imaging System (MDIS) consists of two cameras, a Wide
Angle Camera (WAC) and a Narrow Angle Camera (NAC), mounted on a
common pivot platform. This dataset include regional mosaics of
targeted observations directed at specific regions of interest.
Four types of targeted observations are included:
(a) WAC 3-color targeted observations acquired mainly during
the primary mission, to complement 1 km/pixel 8-color mapping
with a higher spatial resolution 3-color product;
(b) WAC observations of targets that were observed repeatedly at
different photometric geometries in order to improve photometric
models of Mercury; these were observed initially in 8 color and
since early 2013 in 11 colors;
(c) WAC 8- or 11-color science targeted observations; and
(d) NAC image strips acquired either for high-resolution imaging of
morphology or as context for MASCS or MLA observations.
The images in each observation share a common SITE_ID in the
file name and PDS label. The SITE_ID corresponds to a targeting
request entered into a database, in response to which a series of
images was acquired. There is one SITE_ID for each time the
region of interest is observed; thus for photometry targets,
the same geographic region of interest is covered by many sets
of images, each set sharing a common SITE_ID and distinct
photometric geometry.
Each mosaic is map projected in an orthographic projection, and
contains one or more image planes. NAC mosaics contain 4 backplanes:
observation ID, solar incidence angle, emission angle, and phase
angle. WAC color products contain 3 backplanes: solar incidence angle,
emission angle, and phase angle. |
