GeoSyn includes three default lists for tops:
Generic, which are the tops that appear in logs of the current synthetic.
AccuMap System Tops, which are always loaded from your local AccuMap database when you create a new synthetic or launch an existing one. Information for these tops may change following AccuMap data loads.
AccuMap User Tops, which are always loaded from your local AccuMap user tops database when you create a new synthetic or launch an existing one. Information for these tops changes based on your changes.
Create an unlimited number of tops lists with customized display properties that are hidden or shown in the main synthetic display, populate tops lists with check shot or directional survey values, copy tops amongst lists, and delete individual tops in lists. You can't delete the three default lists above, but you can delete the tops within.
