Abstract:
In the era of large surveys and space missions, it is necessary to
rely on large samples of well-characterized stars for
inter-calibrating and comparing measurements from different sources.
Among the most employed photometric systems, the Johnson-Kron-Cousins
has been used for decades and for a large amount of important
datasets. Using Gaia DR3 as a reference, as well as data from
reddening maps, spectroscopic surveys, and variable stars monitoring
surveys, we curated and characterized the widely used Landolt and
Stetson collections of more than 200000 secondary standards, removing
binaries, blends, and variable stars, and we classified and
parametrized them, employing classical as well as machine learning
techniques. In particular, our atmospheric parameters agree
significantly better with spectroscopic ones, compared to other
catalogues obtained by means of machine learning. We also
cross-matched the collections with the major photometric surveys to
provide a comprehensive table with the magnitudes of the secondary
standards in the most widely used photometric systems (ugriz, grizy,
Gaia, Hipparcos, Tycho, 2MASS). We finally provide a set of 167
polynomial transformations, valid for dwarfs and giants, metal-poor
and metal-rich stars, to transform UBVRI magnitudes into the above
photometric systems and vice-versa.
Description:
We provide a curated version of the widely used collections
of secondary standards provided by Landolt and Stetson and their
collaborators.
