Standard Stars in VSP

The 2009 Landolt UBVRI Equatorial Standard Fields are being added to VSP. Descriptions of all the fields are included in the tables below. In order to plot them you need to enter the coordinates and size of the field you want. This table gives the field center coordinates of the fields. Quick link to VSP

NOTES:

  • Field GD71 was taken out because it overlapped onto the comparison star sequence for Z and RU Tauri.
  • No single stars or stars with less than 5 observations are included as standards.
