Abstract:
The Javalambre Photometric Local Universe Survey (J-PLUS) is an
observational campaign that aims to obtain photometry in 12
ultraviolet-visible filters (0.3-1um) over ∼8500deg2 of the sky
observable from Javalambre (Teruel, Spain). Due to its characteristics
and observation strategy, this survey will allow a great number of
Solar System small bodies to be analyzed, and with improved
spectrophotometric resolution with respect to previous large-area
photometric surveys in optical wavelengths.
The main goal of the present work is to present the first catalog of
magnitudes and colors of minor bodies of the Solar System compiled
using the first data release (DR1) of the J-PLUS observational
campaign: the Moving Objects Observed from Javalambre (MOOJa) catalog.
Using the compiled photometric data we obtained very-low-resolution
reflectance (photo)spectra of the asteroids. We first used a
σ-clipping algorithm in order to remove outliers and clean the
data. We then devised a method to select the optimal solar colors in
the J-PLUS photometric system. These solar colors were computed using
two different approaches: on one hand, we used different spectra of
the Sun convolved with the filter transmissions of the J-PLUS system,
and on the other, we selected a group of solar-type stars in the
J-PLUS DR1 according to their computed stellar parameters. Finally, we
used the solar colors to obtain the reflectance spectra of the
asteroids.
We present photometric data in the J-PLUS filters for a total of 3122
minor bodies (3666 before outlier removal), and we discuss the main
issues with the data, as well as some guidelines to solve them.
Description:
As a result of the exploitation of the J-PLUS 1st data release, we
have produced two catalogs with the data of minor bodies in the Solar
System:
1) The first catalog (moojamag.dat) contains all the recovered
magnitudes for a total of 3666 objects, regardless the quality of the
data and the filters in which the objects were observed.
2) The second catalog (moojacol.dat) contains the colors, referred to
the J0515 filter, for a total of 3122 objects, that were filtered
according to the sigma-clipping algorithm, as described in the
manuscript.
