15 Sep 3, 2008NVOSS What About Normal Cell Phones? Usually come w/ smaller screens (e.g. 160x128). Recently 320x200 is common. MVO is a web-app for these small screens. Emphasis on basic query, no data access allowed

16 Sep 3, 2008NVOSS MVO on Cell Phones Resolver mode output pretty basic. Just enough to point a telescope if youre in a field with your telescope but no internet connection.

17 Sep 3, 2008NVOSS MVO on Cell Phones Registry search prints ShortName owing to small screen size Each item is a link that clicks thru to the full Registry record.

18 Sep 3, 2008NVOSS MVO on Cell Phones Registry records prints essential fields. Enough information to know what the resource is, but we restrict printing (e.g. long descriptions) to minimize data transfer.

19 Sep 3, 2008NVOSS MVO on Cell Phones Inventory mode prints a simple count of matched resources and records found in a 10 radius. Result is the resource Title since these are typically Vizier tables. Cluck thru to full resource record
