Atlas is used to select objects on a particular star chart in a printed atlas.
Select Ignore if you want to include objects regardless of appearance in an atlas. If you want to search using one of the other options, you must uncheck Ignore.
Select On ... to choose an atlas and then specify the chart number in the selected atlas. Some of these options may be disabled if an atlas is turned off in Preferences on the Options menu.
What about?
Only the B-series and C-series charts are cross referenced in the Herald-Bobroff AstroAtlas. You can search within either series.
Chart numbering changed radically from the first edition to the second of Uranometria 2000.0. Be sure to select the correct edition for your chart search.
