Abstract (from CDS):

The All-Sky Automated Survey for Supernovae (ASAS-SN) provides long baseline (∼4 yr) light curves for sources brighter than V <= 17 mag across the whole sky. As part of our effort to characterize the variability of all the stellar sources visible in ASAS-SN, we have produced ∼30.1 million V-band light curves for sources in the Southern hemisphere using the APASS DR9 (AAVSO Photometric All-Sky Survey Data Release) catalogue as our input source list. We have systematically searched these sources for variability using a pipeline based on random forest classifiers. We have identified ∼ 220 000 variables, including ∼ 88 300 new discoveries. In particular, we have discovered ∼ 48 000 red pulsating variables, ∼ 23 000 eclipsing binaries, ∼ 2200 δ-Scuti variables, and ∼ 10 200 rotational variables. The light curves and characteristics of the variables are all available through the ASAS-SN variable stars data base (https://asas-sn.osu.edu/variables). The pre-computed ASAS-SN V-band light curves for all the ∼ 30.1 million sources are available through the ASAS-SN photometry data base (https://asas-sn.osu.edu/photometry). This effort will be extended to provide ASAS-SN light curves for sources in the Northern hemisphere and for V <= 17 mag sources across the whole sky that are not included in APASS DR9.

VizieR on-line data: <CDS Catalogue: II/366> : gather 2018MNRAS.477.3145J (N=65270), 2019MNRAS.486.1907J (N=350445), 2019MNRAS.485..961J (N=8848), 2019MNRAS.487.5932P (N=1924), 2020MNRAS.491...13J (N=122648), and 2020MNRAS.493.4186J (N=117367)

Status at CDS : All or part of tables of objects could be ingested in SIMBAD; there are some issues with cross-identifications or classifications.

CDS comments: The resolution of the ASAS-SN survey is 15''. As a consequence the astrometry is poor, usually within 5'', but it can be more than 1 pixel. Status of the catalogue II/366 in SIMBAD : Classical Cepheids (Type = DCEP or DCEPS, N=2183), and Mira Variables (Type = M, N=10230), have been enterely ingested; other LPVs are being processed. Objects with an undefined variability type (Type = VAR, N=62577) will not be ingested.
