Star Proper Motions Based on Two-epoch Observations from the SDSS and DESI Imaging Surveys

Star Proper Motions Based on Two-epoch Observations from the SDSS and DESI Imaging Surveys

In this study, we present the construction of a new proper-motion catalog utilizing the photometric data from the Sloan Digital Sky Survey (SDSS) and Dark Energy Spectroscopic Instrument (DESI) imaging surveys, with a median time baseline of about 13 yr. To mitigate systematic errors, the DESI galax...
