Abstract:
The NIR photometric data of minor planets observed by the VISTA-VHS
survey. This survey uses Y, J, H, and Ks filters for imaging the
entire sky of the southern hemisphere. A total of 39947 Solar System
objects were detected in the VISTA VHS Data Release 3. The detections
found include: 52 NEAs, 325 Mars Crossers, 515 Hungaria asteroids,
38428 Main Belt asteroids, 146 Cybele asteroid, 147 Hilda asteroids,
270 Trojans, 13 comets, 12 Kuiper Belt objects, and Neptune with its 4
satellites. About 34998 of these objects were imaged with at least two
different filters.
Description:
The retrieved photometric data is provided as a set of catalogs called
MOVIS. These catalogs are obtained using a pipeline that finds the
objects based on their ephemeris, retrieves the data by interfacing
with VHS tables, removes the wrong associations, and do a post
processing of the data (averaging, data combine, and colors
computation). The correctness and reliability of the pipeline was
assessed by analyzing the error distributions and by comparing the
results with the 2MASS dataset. The results are reported in three
catalogs: the detections catalog (MOVIS-D), the magnitudes catalog
(MOVIS-M), and the colors catalog (MOVIS-C).

Note (1): Each detection is flagged (first column) with the following code
(corresponding to the flag variable) as follows:
0 = indicates all valid measurements.These measurements passed all sorting
criteria and were used for generating the MOVIS-C, and MOVIS-M catalog
1 = indicates measurements for which the movement rate multiplied by the stack
time interval (trail) is above the specified threshold (1\arcsec)
2 = indicates all the measurements which failed the {O-C} criteria
3 = indicates single night detections for the corresponding object. These
measurements can not be used for color computation or for deriving
photometric properties.
4 = indicates measurements for which the object has neighbors in the searched
box. If the object is in only detected alongside neighbors in one of the
stack frames from that night, then all the measurements from the set were
indicated with code 4;
5 = indicates measurements for which the object overlaps with a background
source, based on the comparison with USNO-B1 catalog
8 = indicates deprecated measurements, i.e. those measurements which are
shown as deprecated or have saturation issues, or
were shown as noise, or are signalized with post-processing error bits.
The flag is computed taking into account the following columns from the
vhsDetection table: {deprecated}, {saturatCorr}, {ppErrBits}, {class}.
