Landolt Bonus Fields

The Landolt (1992) UBVRI photometric standard stars list features several fields which contain multiple standard stars, allowing standards over a range of colors to be measured in a single exposure. The following table lists several of these useful ``bonus fields''. A starlist containing these targets is also available as /kroot/starlists/0000_lris_bonus_fields.
