Solar System Minor Bodies in theJavalambre Variability Survey DR1: The catalog

The Javalambre VARiability Survey (J-VAR) is a photometric survey that is being carried out with the 0.8m Javalambre Auxiliary Survey Telescope (JAST80), located at the Observatorio Astronómico de Javalambre (OAJ, in Teruel). J-VAR is the time-domain extension of the Javalambre-Photometric Local Universe Survey, J-PLUS, carried out in the same telescope. J-VAR uses a sub-set of seven filters from the J-PLUS set covering the range from 0.395 up to 0.861 microns, including the g,r,i filters from the SDSS set. The main concept of J-VAR is to explore the time-domain capabilities offered by the JAST80, and its strategy is as follows: each field is observed three times, with dithering, in all seven filters, and is revisited a total of ten times whenever the weather conditions allow J-VAR to be executed. This observational strategy, favouring the detection of transient phenomena, is also well-suited for the detection of small bodies (SBs) of the Solar System.
Within the 101 fields included in J-VAR Data Release 1 we have recovered more than 130,000 individual detections (an asteroid was detected in one image). These correspond to more than 8,600 objects (a total of 6,572 individual asteroids). The detection of the SBs is done using the SOSS pipeline (Mahlke et al. 2019). Here, we present the first catalog of small bodies of the Solar System observed with J-VAR: we show the calibration method, we present some statistics on the data, and we outline the next steps for future iterations of the catalog.
