VizieR Online Data Catalog: Gaia DR2-based catalogue of 237 Ap stars (Scholz+, 2019)

Except for the main astrometric data from Gaia DR2 we include in our catalogue of 237 strongly magnetic Ap stars astrometric quality criteria that were not given in the original Gaia DR2, information on the existence of close and wide binary companions and open cluster membership, and additional parameters related to photometric quality and possible variability of these objects. The astrometrically most reliable and non-variable stars as well as known close binaries in the catalogue are flagged. For 75 stars already measured by Hipparcos, we provide Hipparcos astrometry, including parameters describing the quality of the data, and photometry. Except for three objects, 2MASS J17380465-2146101, 2MASS J17534913-3332308, and 2MASS J18151324+0121014, the names listed in the catalogue are all resolved by SIMBAD.
