II/355        Sloan magnitudes for the brightest stars, V2    (Mallama, 2018)

A Catalog of Sloan Magnitudes for the Brightest Stars. Version 2. Mallama A. <arXiv, 1805.09324 (2018)> =2018arXiv180509324M =2018yCat.2355....0M
ADC_Keywords: Stars, bright ; Photometry, SDSS Keywords: Photometry, SDSS ; Photometry, ugriz Abstract: A new version of the Catalog containing Sloan magnitudes for the brightest stars is presented. The accuracy of the data indicates that the Catalog is a reliable source of comparison star magnitudes for astronomical photometry. Version 2 complements the APASS database of fainter stars.
